由二取代烯基硼酸[4-substituted-1,2-oxaborol-2(5H)-ol]与N-氯代丁二酰亚胺(NCS)在甲醇中常温反应0.5 h, 可以中等到良好的收率构型保持地合成得到取代的(Z)-3-氯烯丙醇, 产物经1H NMR, 13C NMR, FT-IR, MS 和HRMS 鉴定.通过该方法合成取代的(Z)-3-氯烯丙醇操作简便, 反应条件温和, 收率较高且反应构型能够得到保持.

The chlorination reaction of 4-substituted-1,2-oxaborol-2(5H)-ols with N-chlorosuccinimide (NCS) afford (Z)-2-substituted-3-chloroallyl alcohol in moderate to good yields under the optimized condition. The structures of the products were identified by 1H NMR, 13C NMR, FT-IR and MS techniques. This method is simple, mild, high yield and the configuration is maintained.

Key words: synthesis, alkenylboronic acid, chlorination, (Z)-2-substituted-3-chloro allyl alcohol
