The halogenoacetyl group is a useful protective group for amino compounds, but the known reaction for removing this protective group with thiourea has disadvantages. According to the invention, a halogenoacetyl group is removed from a halogenoactyl amino compound in a short period of reaction time by reacting the halogenoacetyl amino compound with an N-substituted dithiocarbamic acid or a salt thereof. This reaction is useful in the chemical synthesis of compounds containing amino groups.
卤代乙酰基是氨基化合物的一个有用的保护基团,但已知的用硫脲去除该保护基团的反应存在缺点。根据本发明,通过使卤代乙酰氨基化合物与 N-取代二硫代氨基甲酸或其盐反应,可在短时间内从卤代内酰氨基化合物中去除卤代乙酰基。该反应可用于含有氨基的化合物的化学合成。
