2- (Phenylthio)-2-penten-5-olide, readily accessible from δ-valelolactone, showed high electrophilic reactivities toward some typical carbon nucleophiles to give 3-substituted 2-(phenylthio)pentanolides, which were convertible to a variety of 3-substituted pentan-5-olides and 2-penten-5-olides.
2-(苯硫基)-2-penten-5-内酯,易从δ-valelolactone获得,对一些典型的碳亲核试剂表现出较高的电亲和性,可以生成3-取代的2-(苯硫基)五醇内酯,进一步转化为多种3-取代的戊烯-5-内酯和2-penten-5-内酯。
