In this work we describe the synthesis of some novel fused imidazo [2, 1-b] [1, 3] thiazole derivatives. The reaction of 1, 2-diaminoethane 1 with carbon disulphide in H2O/ETOH as solvent furnishes 4, 5-dihydro-1H-imidazol-2-thiol 2 under reflux condition. the reaction of 4,5-dihydro-1H-imidazol-2-thiol on treatment with ethylchloro acetate and aromatic aldehyde in presence of anhydrous sodium acetate and acetic acid as solvent to give (Z)-2-(arylidene)-5,6-dihydroimidazo [2,1-b] [1,3] thiazol-3(2H)-one 3a-j. Compounds 3a-j was condensed with hydroxylamine to give 3-(aryl)-2, 3, 6, 7-tetrahydroimidazo [2, 1-b] [1,3] thiazolo [5, 4-d] isoxazole 4a-j. The structures of the new compounds were established by elemental analyses, IR,1H NMR and13C NMR data.

A number of new complexes have been synthesized by reaction of novel ligands acetic acid(4-methyl-benzylidene)hydrazide (L1) and acetic acid(naphthalen-1-ylmethylene)hydrazide (L2) with copper(II) nitrate. These new compounds were characterized by elemental analysis, TG, DTA, IR spectroscopy, UV spectral techniques. The changes observed between the FT-IR and UV-Vis spectra of the ligands and of the complexes allowed us to establish the coordination mode of the metal in complexes. The results suggest that the Schiff bases L1and L2coordinate as univalent anions with their bidentate N,O donors derived from the carbonyl and azomethine nitrogen. Also the probing of thermal analysis complexes can detect which complex has excellent thermal stability.

In this article, acid hydrazide 2, a functional group, was synthesized by the reaction of (4-chloro-12- methyl-16,17-dihydro-15-thia-6,11-diaza-cyclopenta[a]phenanthren-7-ylsulfanyl)acetic acid ethyl ester (1) with hydrazine yield (4-chloro-12-methyl-16,17-dihydro-15-thia-6,11-diazacyclopenta[a]- phenanthren-7-ylsulfanyl)acetic acid hydrazide (2) is discussed. The reactive acid hydrazide compound 2 was utilized for the synthesis of amides 3, Schiff’s bases 4 and thiazolidine 5 derivatives. The structures of target compounds were confirmed by elemental analysis and spectral data. The antimicrobial activity of new compounds were studied against Streptococcus sp., Bacillus megaterium, Staphylococcus aureus, Escherichia coli, Bacillus cereus, Bacillus subtilis, Proteus valgaris and Pseudomonas aeroginosa by the agar well diffusion method. Compounds 4b, 5a, 5b and 5c showed good antimicrobial activity

In this paper the new starting material 2-(5-chloro-1H-benzo[d]imidazole-2-yl) aniline (1) was synthesized by the condensation reaction of 4-chloro-o-phenylenediamine and anthranilic acid .The new Mannich base derivatives were synthesized using formaldehyde and different secondary amines to synthesize a new set of benzimidazole derivatives(2-5). Also, the new Schiff-base derivatives (6-10) were synthesized from the reaction of compound (1) with various aromatic aldehydes and the closure-ring was done successfully using mercapto acetic acid to get the new thiazolidine derivatives(11-12).These new compounds were characterized using some physical techniques like:FT-IR Spectra and 1HNMR Spectra.

The preparation of halogenotrimolybdate(II) compounds containing the staphylonuclear groups, (Mo3Cl13)7-, (Mo3Br13)7-, (Mo3Cl12)6-,(Mo3Cl11)5-, (Mo3Br11)5-, (Mo3Br11)5- has been thoroughly examined and 11 new compounds are reported. No iodomolybdate(II) compounds were observed. When (NH4)7Mo3Cl13,H2O is heated in vacuum, ammonium chloride is evolved but the final product is never MoCl2. This chloromolybdate(II) undergoes rapid reaction with refluxing acetic acid to give an approximately two-thirds yield of molybdenum(II) acetate. This suggests the cleaving of an Mo3 group to give Mo2(CH3CO2)4. Crystalline [Co en3]3Mo3Cl15,6H2O undergoes spontaneous intramolecular redox reaction which is stimulated by light, or moisture, but not oxygen.

Condensation of 5-methoxycarbonyl-2-furfuryl trichloromethyl sulfone with 4-X-benzaldehydes (X = H, OH, OCH3, N(CH3)2, Cl, I, CN) or 5-Y-2-furaldehydes (Y = H, NO2) in acetic acid in the presence of ammonium acetate and piperidine afforded the corresponding 1-(5-methoxycarbonyl-2-furyl)-1-trichloromethylsulfonyl-2-arylethylenes (IIa-IIj). Structure of these new compounds is discussed on the basis of their UV, 1H-NMR and IR spectra.

Heating of 8-methylthiodibenzo[b,f]thiepin-10(11H)-one with mono-p-toluenesulfonates of 1-methylpiperazine and piperazine in vacuo led in good yields to the enamines IX-XI, the first of which was reduced with zinc and acetic acid to the base I (methiothepin). The ester III(oxyprothepindecanoate) was obtained by reaction of the amino alcohol II (oxyprothepin) with decanoic acid in the presence of N,N'-carbonyldiimidazole and by substitution of 10-chloro-8-methylthio-10,11-dihydrobenzo[b,f]thiepin with 1-(3-decanoyloxypropyl)piperazine. The substitution reaction of the same chloro compound with piperazine gave two stereoisomeric 1,4-disubstituted piperazines V. Reaction of the amino alcohol II with octyl isocyanate afforded the carbamate VI, an isoster of oxyprothepin decanoate (III). This substance showed in the test of antiapomorphine activity in dogs the properties of a long-acting antiemetic. Two new potential metabolites (XII, XIII) of compounds I-III were synthesized and new pharmacological data are given for two further potential metabolites (XIV, XV) of oxyprothepin (II).
