REGIO- AND DIASTEREOSELECTIVE ALKYLATION OF (1R,5S)-4-ETHYL-6,6-DIMETHYL-3-(PHENYLSULFONYL)BICYCLOHEPT-3-EN-2-ONE

Alkylation of (1R,5S)-4-ethyl-6,6-dimethyl-3-(phenylsulfonyl)bicyclohept-3-en-2-one (3) with allyl bromide proceeded at the γ position to the conjugated enone system in regio- and diastereoselective fashion, providing (1R,5S)-4-((1R)-1-methyl-3-but
