The N-alkylation of the two title compounds was studied, utilizing phase transfer catalysis (PTC) methods. Very mild reaction conditions were developed, especially for three-carbon N-alkylation. Of special interest is the high-yield synthesis of N-(3-chloropropyl)-2-chlorophenothiazine. The results are discussed in terms of the classical PTC/OH− mechanisms.
利用相转移催化(PTC)方法研究了两种标题化合物的N-烷基化。已经开发出非常温和的反应条件,特别是对于三碳N-烷基化。特别令人感兴趣的是N-(3-氯丙基)-2-氯吩噻嗪的高产率合成。结果列于经典PTC / OH来讨论-机制。
