以4-、5-、6-和7-氯吲哚(2a-d)为原料,通过色氨酸合成酶与L-丝氨酸反应,制备了4-氯-L-色氨酸(1a)、5-氯-L-色氨酸(1b)、6-氯-L-色氨酸(1c)和7-氯-L-色氨酸(1d)。氯代正丁醇是光学纯的(> 99%e.e)。
4-Chloro-L-tryptophan (1a), 5-chloro-L-tryptophan (1b), 6-chloro-L-tryptophan (1c) and 7-chloro-L-tryptophan (1d) were prepared from 4-, 5-, 6- and 7-chloroindoles (2a-d) by reaction with L-serine using tryptophan synthase. The chlorotryptophans were optically pure (>99% e.e).
