Substituted 2,5-dihydrothiophene S,S-dioxides, which are stable precursors of the corresponding buta-1,3-dienes, were prepared via reactions of 3-methylene-2,3-dihydrothiophene S,S-dioxide with electrophiles and nucleophiles; this method was applied to the synthesis of (±)-ipsenol.
通过3-亚甲基-2,3-二氢噻吩S,S-二氧化物与亲电子试剂和亲核试剂的反应制备了取代的2,5-二氢噻吩S,S-二氧化物,它们是相应的buta-1,3-二烯的稳定前体。; 该方法用于合成(±)-异丙酚。
