Abstract
Generation of a mixed anhydride using ethyl or isopropyl chloroformate and N-methylmorpholine in dichloromethane at room temperature, followed by addition of excess ring-substituted phenol or N-substituted hydroxylamine and a catalytic amount of tertiary amine, provides an efficient synthesis of activated esters.
摘要
在室温下于二氯甲烷中使用氯甲酸乙酯或氯甲酸异丙酯与N-甲基吗啉生成混合酸酐，随后加入过量的环取代苯酚或N-取代羟胺以及催化量的叔胺，可实现活性酯的高效合成。
