Jaspine B and its C-2 and/or C3 epimers have been enantio-selectively prepared from butadiene monoepoxide through a synthetic procedure consisting of allylic amination by palladium-catalyzed dynamic kinetic asymmetric transformation, cross metathesis, and stereoselective dihydroxylation as key steps.
Jaspine B 及其 C-2 和/或 C3 差向异构体已经从丁二烯单环氧化物通过合成程序对映选择性制备,该合成程序包括通过钯催化的动态动力学不对称转化、交叉复分解和立体选择性二羟基化的烯丙基胺化作为关键步骤。
