α-Alkoxycarbonylketene dithioacetals (1) were smoothly reduced by the higher order cyanocuprate Me2Cu(CN)Li2 at –20 °C to the corresponding vinyl sulphides (2) in high yields, with high stereoselectivity and generality.
α-烷氧基羰基乙烯酮二硫缩醛(1)在–20°C下被高阶氰铜酸盐Me 2 Cu(CN)Li 2平稳地还原成相应的乙烯基硫化物(2),具有高的立体选择性和通用性。
