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
4-氟脯氨酸是化学生物学中最有用的非天然氨基酸之一。在这里,报道了合成 4-氟脯氨酸的 2S,4R、2S,4S 和 2R,4S 非对映异构体的实用路线。每条路线都从 (2S,4R)-4-羟脯氨酸开始,它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,这些路线提供了对这些有用的非天然氨基酸的工艺规模访问。
