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–Backlund type elimination of p-toluenesulfinate and SO2, is here applied to the synthesis of 3-alkyl-3-cyclopentenones.
一种新的通用烯烃合成,通过 α-(p-tolylsulfonyl)thiane S,S-dioxide、1,4-dioxa-7-p-tolylsulfonyl-8-thiaspiro[4.5]decane 8,8-dioxide 和随后对甲苯亚磺酸盐和 SO2 的 Ramberg-Backlund 型消除在这里应用于 3-烷基-3-环戊烯酮的合成。
