✦ Synopsis

Interesting reactivitics have baen observed upon reaction of epoxy-spiroketal 1 with a variety of dimethyl-aluminum sulfides, and are compared with results obtained upon reaction of the same epoxide 1 with diethyl alu&um cyanide. These chemical modifications provide access to novel avermeuin Bb analogs possessing interesting biological pmperties.
