Abstract

A new general olefin synthesis, via regioselective alkylation of α-(p-tolylsulfonyl) thiane S, S- dioxide, 1, 4-dioxa-7-p-tolylsulfonyl-8-thiaspiro [4.5] decane 8, 8-dioxide, and subsequent Ramberg–Bäcklund type elimination of p-toluenesulfinate and SO 2, is here applied to the synthesis of 3-alkyl-3-cyclopentenones.
