synthetic protocol for the preparation of a new class of morpholino homonucleosides in enantiopure form starting from readily available 1,2-aminoalcohols or glycidol has been developed. Key intermediates of the synthetic sequence are 2-bromomethyl morpholines, diastereoselectively achieved from the corresponding alkenols by palladaelectro-catalyzed alkoxybromination of unactivated alkenes. The so obtained
已经开发出一种合成方案,用于从容易获得的 1,2-氨基醇或缩水甘油开始制备对映体纯形式的新型吗啉代同核苷。合成序列的关键中间体是 2-溴甲基吗啉,通过 pallada 电催化未活化烯烃的烷氧基溴化,从相应的烯醇非对映选择性地获得。如此获得的溴代衍生物又易于被核酸碱基官能化,以便于获得吗啉代同核苷。
