4-氟脯氨酸是化学生物学中最有用的非天然氨基酸之一。本文报道了合成4-氟脯氨酸的2S,4 R,2S,4S和2 R,4S非对映体的实用路线。每种途径都从(2S,4 R)-4-羟脯氨酸开始,这是胶原蛋白的主要成分,因此很容易获得,并使用氟化物盐来安装氟基团。因此,这些途径提供了对这些有用的非天然氨基酸的工艺规模的获取。(c)2008 Elsevier B. V.保留所有权利。
4-Fluoroprolines are among the most useful nonnatural amino acids in chemical biology. Here, practical routes are reported for the synthesis of the 2S, 4R, 2S, 4S, and 2R,4S diastereomers of 4-fluoroproline. Each route starts with (2S,4R)-4-hydroxyproline, which is a prevalent component of collagen and hence readily available, and uses a fluoride salt to install the fluoro group. Hence, the routes provide process-scale access to these useful nonnatural amino acids. (c) 2008 Elsevier B.V. All rights reserved.
