benzothiazole with trimethylsilyl cyanide and an acid chloride in CH2Cl2 gives the N-acyl-2-cyano-2,3-dihydrobenzothiazole in good yield; benzoxazole similarly is converted into a five-membered ring Reissert compound, providing the first examples in these series.
在CH 2 Cl 2中用三甲基甲硅烷基氰化物和酰氯处理苯并噻唑,得到的N-酰基-2-氰基-2,3-二氢苯并噻唑具有良好的收率。苯并恶唑类似地被转化为五元环的Reissert化合物,提供了这些系列中的第一个实例。
