Condensation of the triisobutylaluminum complex of cysteamine HCl with a variety of carboxylic esters furnishes thiazolines in one step. This new method has been applied to chiral α-aminoesters to give α-amino thiazolines of high optical purity, yet N-benzyl protection of the amine is required.
半胱胺盐酸盐的三异丁基铝络合物与多种羧酸酯的缩合一步即可提供噻唑啉。该新方法已应用于手性α-氨基酯,以得到高光学纯度的α-氨基噻唑啉,但仍需要胺的N-苄基保护。
