✦ Synopsis

Some sesquiterpenes having a-methylene-y-lactone moiety are worthy of attention to the cytotoxlc and antl-tumor activities.

The transformation procedures of a-methyl-y-lactones into a-methylene-y-lactones have been reported by many workers. 3 Very recently, Grieco et al.

3 --

reported that a-methylene-ylactone compounds were prepared via phenylselenlde derlvatlves in good yield

Several furanosidic derivatives have been found to have biological activity and have been used both as fungicides and plant growth regulators. In particular, those carbohydrate derivatives that contain the a-methyleney lactone unit have interesting potential applications. The present study deals wit
