Interesting reactivities have been 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 aluminum cyanide. These chemical modifications provide access to novel avermectin B2a analogs possessing interesting biological properties.
