The title thiacrown ethers were prepared in a one-step procedure to give a series of unique macrocycles possessing two unsubstituted hydroxy groups that can be easily functionalized. In addition, epoxides and macrocycles derived from Cookson’s birdcage diketone, were prepared. The nucleophilic ring opening of epoxides synthesis can be classified in the frame of click chemistry. Surprisingly, some of the prepared allyl substituted polyglycols as well as bis-epoxides, especially sulfur analogues, were prepared for the first time.

Ring Opening Of Epoxides

A novel and unusual approach based on a ClCF2COONa–DMF system has been developed for the synthesis of chlorohydrins via an unexpected mechanism. In a first ever report for the synthesis of chlorohydrins from glycidyl ethers, e.g., CH2=CH-CH2-O-Z, CH3CH2-O-Z, C6H5-O-Z, C6H4(o-CH3)-O-Z, CH2=C(CH3)C(=O)-O-Z, etc., (where Z = glycidyl), difluorocarbene-induced facile regioselective ring opening of epoxides has generated the compound in high yield (70%–83%). [Formula: see text] Key words: difluorocarbene, sodium chlorodifluoroacetate, chlorohydrins.
