The reduction of alkyl 2,4-alkadienoates, bearing alkyl substituents on the diene system, with sodium dithionite, under phase transfer conditions, gives satisfactory yields of E:Z isomeric mixtures of the corresponding 3-alkenoates, except in the case of the C-2 substituted substrate which afforded the E-3-alkenoate as the only reduction product.
在相转移条件下,用连二亚硫酸钠还原在二烯系统上带有烷基取代基的2,4-链二烯酸烷基酯,得到令人满意的相应3-链烯酸酯的E:Z异构体混合物的产率,除了C -2取代的底物,其提供唯一的还原产物E-3-链烯酸酯。
