The reaction of 1,7-enynes, synthesised from α-amino acids, carried out with diazo compounds in the presence of the Cp*RuCl(cod) catalyst allowed the one-step preparation of various strained bicyclic pipecolic acid derivatives in good yields under mild conditions. The stereoselectivity of the created double bond depends on the nature of the diazoalkane, and the diastereoselectivity arises essentially
在 Cp*RuCl(cod) 催化剂存在下,由 α-氨基酸合成的 1,7-烯炔与重氮化合物的反应允许以良好的收率一步制备各种应变双环哌啶酸衍生物。条件温和。生成的双键的立体选择性取决于重氮烷烃的性质,非对映选择性主要来自空间因素。
