Preparation of alkyl-substituted indoles in the benzene portion. Part 12. Enantiospecific synthesis of hapalindole O

An important chiral ketone derivative, (3S,4R)-3-methyl-4-pivaloyloxy-3- vinylcyclohexan-1-one (16) was prepared from (R)-(-)-carvone (10) using a stereo-controlled conjugate addition of the vinyl group to (R)-3-methyl-6- (1-methylethylidene)-4-pivaloylox
