โœฆ Synopsis


Trimethylsilyl group substituted bicyclo[Z.Z.Zloctane derivatives were synthesized and subjected to TMS group directed Wagner-Meerwein rearrangement to give bicyclo[3.2.lloctene derivatives in high yields.

In connection with projected total syntheses of some natural products utilizing 5-trimethylsilyl-2-cyclohexenone (l),')

we examined the synthesis of
