通过在2位带有各种β和γ-氨基醇的嘧啶9或嘧啶酮10的分子内环化反应,合成了几种类型1和2的咪唑基和嘧啶并[1,2- a ]嘧啶酮。在Mitsunobu条件下10型嘧啶酮的闭环会产生双环区域异构体1和2的混合物。用H 2 SO 4处理9型嘧啶为获得咪唑和嘧啶[1,2- a ]嘧啶酮提供了有效且操作简单的一锅水解-环化程序作为唯一的区域异构双环产物,收率良好,为1。
A simple synthetic method for the preparation of optically active pyrimidinyl α-amino acids is presented. A nucleophilic ipso-substitution reaction between 2-(benzylsulfonyl)-4-isopropoxypyrimidines and a nucleophilic side chain of several protected natural α-amino acids is investigated to obtain new pyrimidin-2-yl α-amino acids. A detailed optimisation study of this reaction is discussed. Moreover
