An efficient stereoselective synthesis of dendrobate alkaloid (+)-241D and its C-4 epimer was achieved from the inexpensive, commercially available starting material decanal (10) in an overall yield of 21.9% and 21.1%, respectively. This synthesis utilizes the key steps of Maruoka asymmetric allylation, one-pot epoxidation followed by nucleophilic addition of an organomagnesium reagent (Forsyth’s protocol)
由便宜的可商购的起始原料de(10)实现了树状生物碱(+)-241D及其C-4差向异构体的有效立体选择性合成,总收率分别为21.9%和21.1%。该合成利用了Maruoka不对称烯丙基化,一锅环氧化,随后亲核添加有机镁试剂(Forsyth规程)和随后的官能团转化的关键步骤。
