The bromination, the nitration, the chlorosulfonation, the formylation and the Mannich reaction of 1, 2-benzisothiaizol-3-acetic acid (1) were investigated and it was shown that the 3α-methylene group is also activated to the electrophilic substitutions as in 1, 2-benzisoxazol-3-acetic acid.
研究了 1,2-苯并异噁唑-3-乙酸(1)的溴化、硝化、氯磺化、甲酰化和曼尼希反应,结果表明 3α-亚甲基也能像 1,2-苯并异噁唑-3-乙酸中的亲电取代那样被激活。
