The use of β-nitroenamines as a new class of acceptors in the enantioselective Pd-catalyzed trimethylenemethane cycloaddition afforded differentiated 1,2-dinitrogen bearing cyclopentanes with three contiguous stereocenters. The utility of these acceptors was demonstrated with the efficient construction of the core of jogyamycin and aminocyclopentitols. Further elaboration of the cycloadducts provided
在对映选择性的Pd催化的三亚甲基甲烷环加成反应中,将β-亚硝胺用作新型受体,可得到带有三个连续立体中心的,带有1,2-二氮的环戊烷。这些受体的效用通过有效的缓霉素和氨基环戊糖醇核心的构造得到证明。环加合物的进一步加工提供了一种针对Joygamycin的简明合成方法。
