The electrophile-initiated cyclization of some 2-allylanilines and their amide derivatives has been further investigated. Although 2-allylanilines with small, allylic substituents such as methyl reacted with iodine to yield 3-iodo-1,2,3,4-tetrahydroquinolines the 2-allylanilines with larger substituents related to those of virantmycin provided low yields of the tetrahydroquinoline as part of a complex product mixture.
我们进一步研究了一些 2-烯丙基苯胺及其酰胺衍生物的亲电引发的环化反应。虽然甲基等烯丙基取代基较小的 2-烯丙基苯胺与碘反应生成了 3-碘-1,2,3,4-四氢喹啉,但与病毒霉素的取代基有关的取代基较大的 2-烯丙基苯胺作为复杂产物混合物的一部分,其四氢喹啉的产量较低。
