摘要 L-色氨酸在碱性条件下消旋制得DL-色氨酸,以D-樟脑磺酸为手性拆分剂生成D-色氨酸樟脑磺酸盐,最后经水解制得D-色氨酸,总收率约40%。 Started from L-tryptophan, DL-tryptophan was obtained by racemization in the basic condition. Then DL-tryptophan was resoluted to D-tryptophan camphorsulfonate using D-camphorsulphonic acid as resolving agent. After the hydrolysis reaction, D-tryptophan could be afforded with an overall yield of about 40 %.
