Reactions of 2-bromobenzyl bromide and its analogues XVII and XXV with 2-hydroxythiophenol resulted in 11H-dibenz[b,f]-1,4-oxathiepin (Ia) and its 2-chloro (Ib) and 2-trifluoromethyl derivative (IC). Treatment of the lithium compounds derived from Ia and Ib with carbon dioxide and dimethylaminoalkyl chlorides gave compounds IIa, Va and VIab; modification of side chains led to amines IVa, VIIa and VIIIa. 11-(1-Methyl-4-piperidyl) derivatives Xbc were obtained by chlorination of compounds Ibc with sulfuryl chloride or N-chlorosuccinimide and the following treatment with 1-methyl-4-piperidylmagnesium chloride. Compound Ib was transformed by oxidation to the sulfone XX affording by treatment with sodium hydride and tert-aminoalkylchlorides the basic sulfones XXI and XXII. While the nuclearly unsubstituted amines with the aliphatic side chains (IVa and VIIa) have intensive antireserpine activity and are potential antidepressants, the 11-(1-methyl-4-piperidyl) derivatives with a substituent in position 2 of the skeleton (Xbc) are potential neuroleptics; the trifluoromethyl derivative Xc especially has outstanding cataleptic and antiapomorphine efficacy.

1-[2-(2-Fluorophenoxy)phenyl]-4-dimethylaminobutanol (XI) was synthesized from 2-(2-fluorophenoxy)benzoic acid (VIII) in three steps and cyclized with sodium hydride in dimethylformamide to the title compound V. Reaction of 5-chloro-2-(methylthio)thiophenol (XIV) with sodium and liquid ammonia afforded benzene-1,2-dithiol (XIII) which was treated with 2-bromobenzyl bromide and gave 11H-dibenzo[b,e]-1,4-dithiepin (II). An alternative synthesis of compound II consisted in the cyclization of 2-(2-bromophenylthiomethyl)thiophenol (XVIII) and was accompanied by the simultaneous formation of 6H, 12H-dibenzo[b,f]-1,5-dithiocin (XIX) and thianthrene (XX). Reaction of compound II with n-butyllithium and the following treatment with dimethylaminoalkyl chlorides or with carbon dioxide resulted on the one hand in two further title compounds VI and VII, and in the carboxylic acid XXI on the other. 2-Chloro-11H-dibenzo[b,e]-1,4-dithiepin (XXII) was obtained by a further synthesis alternative using in the first step the cyclization of 2-(4-chloro-2-chloromethylphenylthio)thiophenol (XXV). Compound VI and VII showed a high degree of activity in the test of antagonization of reserpine hypothermia in mice.

2-(2-Fluorophenylthio)benzaldehydes IXa-c and 5-chloro-2-(2-fluorophenylthio)acetophenone were treated with 1-methyl-4-piperidylmagnesium chloride and 3-dimethylaminopropylmagnesium chloride, respectively, and the resulting amino alcohols VIa-c, XVII and XVIII were cyclized with sodium hydride in dimethylformamide. In addition to the title compounds Ia-c, XIX and XX, several types of by-products were obtained. Demethylation of compound Ib by the chloroformate method afforded the secondary amine IIb which was transformed to the amino alcohols IIIb and Vb. Compounds Ia-c are very potent neuroleptics with a high degree of central depressant and cataleptic activity. The amino alcohol Vb exhibits a very strong antiapomorphine effect in rats.

The aldehydes VIa and VIb were transformed by treatment with chloroform and sodium hydroxide in the presence of triethylbenzylammonium chloride to the α-chloro acids VIIa and VIIb which were demethylated with boron tribromide and the products were cyclized with sodium hydroxide in dimethyl sulfoxide to 2-fluoro-6H-dibenz[b,e]-1,4-oxathiepin-6-carboxylic acids Ia and Ib. Syntheses of the aldehydes XVIIbcd were carried out and the products treated with 1-methyl-4-piperidylmagnesium chloride to give the amino alcohols XVIbcd. Cyclizations with sodium hydride in dimethylformamide afforded the title compounds XIIbcd; compounds XVIIIbc and XIX were isolated as by-products and characterized. Compound XIIb was transformed via the secondary amine XIIIb to the amino alcohol XIVb which was esterified to the decanoate XVb. Substances XIIbcd are highly active neuroleptic agents with an important prolongation of the central depressant effect. The decanoate XVb revealed the properties of a medium long acting depot neuroleptic.

To study the effect of β-substitution in 2'-alkyl derivatives of 9-(2-phosphonomethoxyethyl)adenine (Ia) on the antiviral activity or group specificity, these derivatives were synthesized. 9-(2-Hydroxyalkyl)adenines VIII were prepared by alkylation of adenine with suitably substituted oxiranes XIII or 2-hydroxyalkyl p-toluenesulfonates IV and VI. After protection of the adenine amino group by benzoylation (compounds IX) or amidine formation (compounds X), the intermediates were alkylated with diisopropyl p-toluenesulfonyloxymethanephosphonate (XI) in the presence of sodium hydride. After deprotection, the obtained phosphonate diesters XII were converted into phosphonic acids I by transsilylation and hydrolysis. This synthetic scheme was used for the preparation of ethyl (Ie), propyl (If), 2-propyl (Ig), 2-methylpropyl (Ih), cyclopropyl (Ii), cyclohexyl (Ij), benzyl (Ik) and phenyl (Il) derivatives. The 2'-trifluoromethyl derivative XXIIa was prepared analogously from 9-(2-hydroxy-3,3,3-trifluoropropyl)adenine (XXa), obtained by alkylation of adenine sodium salt with 2-hydroxy-3,3,3-trifluoropropyl bromide. 2'-Trimethylsilyl derivative XIXa was obtained by alkylation of adenine with 2-diisopropylphosphonomethoxy-3-(4-toluenesulfonyloxy)propyltrimethylsilane (XVII) followed by transsilylation and hydrolysis of diester XVIIIa. 2,6-Diaminopurine derivatives XVIIId and XXIIb were obtained analogously. 9-(3-Phosphonomethoxybutyl)adenine (XXVIII) and 9-(2-methyl-2-phosphonomethoxypropyl)adenine (XXXV) were prepared from the corresponding hydroxy derivatives XXVIb and XXXII, respectively, by the same reaction pathway as derivatives I.

Heating of 2-(2-hydroxyphenylthio)benzoic acid (XX) with acetic anhydride gave dibenz[b,e]-1,4-oxathiepin-6-one (XXII). Demethylation of 2-(2-methoxyphenylthio)benzyl bromide (XI) with boron tribromide and the following treatment with aqueous sodium hydroxide in dimethyl sulfoxide afforded 6H-dibenz[b,e]-1,4-oxathiepin (I) which was halogenated with chlorine or N-bromosuccinimide only to the undesirable 2-halogeno derivatives II and III. A reaction of 2-(2-methoxyphenylthio)benzaldehyde (XII) with chloroform and 50% aqueous sodium hydroxide in the presence of triethylbenzylammonium chloride led to the α-chloro acid XIX whose demethylation with boron tribromide and the following cyclization with sodium hydroxide in dimethyl sulfoxide gave a mixture with prevailing 6H-dibenz[b,e]-1,4-oxathiepin-6-carboxylic acid (IV). Amino alcohols XXV-XXVIII were obtained by reactions of 2-(2-fluorophenylthio)benzaldehyde (XXIV) with the corresponding Grignard reagents and the products were cyclized with sodium hydride in dimethylformamide to the title compounds V-VIII. While compounds V and VI showed antireserpine effects and can be considered as potential antidepresants, compound VIII has a strong central depressant activity, brings about ataxia, hypothermia and potentiates the cataleptic action of neuroleptics (properties of a tranquillizer).

The syntheses of new BEDT-TTF derivatives are described. These comprise BEDT-TTF with one ethynyl group (HC≡C-), with two (n-heptyl) or four (n-butyl) alkyl side chains, with two trans acetal (-CH(OMe)2) groups, with two trans aminomethyl (-CH2NH2) groups, and with an iminodiacetate (-CH2N(CH2CO2−)2 side chain. Three transition metal salts have been prepared from the latter donor, and their magnetic properties are reported. Three tris-donor systems are reported bearing three BEDT-TTF derivatives with ester links to a core derived from benzene-1,3,5-tricarboxylic acid. The stereochemistry and molecular structure of the donors are discussed. X-ray crystal structures of two BEDT-TTF donors are reported: one with two CH(OMe)2 groups and with one a -CH2N(CH2CO2Me)2 side chain.
