synthetic method for the preparation of allyl amines has been developed. The key steps of this method are enantioselective addition of diethylzinc and [1,3]-chirality transfer through the [3.3] sigmatropic rearrangement of allyl cyanates. Stereocontrolled syntheses of lentiginosine (1) and polyoxamic acid derivative 2 from a common intermediate 7 derived from D-tartaric acid (8), have been accomplished.
已经开发出一种新的制备烯丙基胺的合成方法。该方法的关键步骤是二乙基锌的对映选择性加成和通过[3.3]烯丙基氰酸酯的σ重排而进行的[1,3]-手性转移。已从衍生自D-酒石酸(8)的常见中间体7进行了立体控制的龙胆草碱(1)和聚草酰胺酸衍生物2的立体合成。
