A concise synthetic approach to optically active taxol C-ring fragment

A concise synthetic approach to an optically active taxol C-ring fragment starting from a readily available compound is described. Lewis acid promoted-cyclization of optically active epoxy trimethylsilane 7 affords the key intermediate 8 in 69% yield (at 91% conversion). Further transformation of 8 to our taxol C-ring fragment is successfully achieved in a stereoselective manner.
