A preferential 1,2 elimination reaction of syn diethyl (2-acetylamino-1-bromo-2-(p-methoxy- phenyl)ethyl)phosphonate 1 rather than the anticipated nucleophilic substitution reaction under basic conditions is described in the present paper.
与文献 报道的甲基磺酸酯离去基团相比,在碳酸钾存在下,反应原料中的α- 溴原子作为相对较弱的离去基团导致很 低的转化率;而在1,8 -二氮杂双环[5,4,0] -十一碳 -7 -烯(DBU)存在下,由于α- 溴原子较强的电负性,其诱导 作用使得邻位β- 氢原子较易与碱作用,因而导致1,2消除反应。
