Simple syntheses of homochiral (Z)- and (E)-1-methoxy-3-alkylsulfinyl-1,3-butadienes were provided by the cycloaddition of (IS)-d-isobornyl-10-sulfenic acid to (Z)- and (E)-1-methoxybut-1-en-3-yne. Asymmetric induction pertained for such cycloadditions, which also provided homochiral dienes from 1-ethynylcyclohex-1-ene.
