The base promoted addition of 3-methyl-2-butenyl phenyl sulfide to aldehydes and ketones occurred selectively on the γ-position of the allylic moiety. The product was converted to the methanesulfonate. Treatment of the resulting homoallylic ester with nucleophiles induced the cyclization to give cyclopropane derivatives in excellent yields.
