Functionalised indolines have been prepared by treating
tetrathiafulvalene (TTF) with
2-(N-acyl-N
-allylamino)benzenediazonium tetrafluoroborates.
N-Benzoyl-protected substrates afford complex reaction
mixtures due to competing radical cyclisation onto the benzoyl group.
Acetamides react more efficiently affording good yields of product
alcohols when the reactions are carried out in moist acetone
功能化
吲哚啉是通过将
四硫富瓦烯(
TTF)与2-(N-酰基-N-
丙烯基
氨基)苯二氮杂烷四
氟硼酸盐处理而制备的。N-苯甲酰保护的底物由于与苯甲酰基的竞争自由基环加成,导致反应混合物复杂。而当在
潮湿的
丙酮中进行反应时,乙酰胺的反应效率更高,能够获得良产率的产物
醇类。
