✦ Synopsis


3-(Difluoromethylene)-4,4-dimethyloxolan-2-one, prepared by difluoromethylenation of 4,4-dimethyloxolan-2,3-dione, exhibits marked reactivity toward nucleophilic reagents. a-Methylene-y-lactone structure is found in many naturally occurring terpenes and some of them are known to exhibit biological activities. Encouraged by this nature, a large number of synthetic m,ethods to construct this unique functional moiety have been developed by now. 1) As a part of our

Sulfination of brorrrodifluoroacetate or acetaitiide 1 with sodiurrr dithionite gives the corresponding sulfinates 2a and 2b, respectively, which upon cuprous bromide catalyzed allylation afford the allylsulfonyldifluoroacetate and acetatnides. Phenyl-or alkylsulfonyldifluoroacetates and acetamides
