glyoxalate was converted into the trichloroacetimidate that in the presence of DABCO rearranged to the corresponding trichloroacetamide. Eventually, hydrolysis under acidic conditions, led to the hydrochloride of racemic β-methyleneaspartic acid.
将 丙烯酸甲酯和乙二醛乙酯的 Baylis-Hillman 加合物转化为三氯乙亚氨酸酯,在 DABCO 存在下将其重排为相应的三氯乙酰胺 。最终,在酸性条件下水解,产生外消旋β-亚甲基天冬氨酸的盐酸盐。
