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
提出了一种简单的合成方法,用于制备旋光嘧啶基α-氨基酸。研究了2-(苄基磺酰基)-4-异丙氧基嘧啶和几种受保护的天然α-氨基酸的亲核侧链之间的亲核ipso取代反应,以获得新的嘧啶-2-基α-氨基酸。讨论了该反应的详细优化研究。此外,研究了在Mitsunobu条件下用一些天然α-氨基酸的羟基侧链对2-(苄基硫烷基)-4(3H)嘧啶酮进行选择性O-烷基化的方法,作为制备新嘧啶丁-4-基α-的方法。氨基酯。
