Alkenes, arenes, and heteroarenes possessing an 8-quinolylamide group as the directing group are alkylated with primary and secondary alkyl tosylates, mesylate, and halides in the presence of Fe(acac)3/diphosphine as a catalyst and ArZnBr as a base. The reaction proceeds stereospecifically for alkene substrates and takes place without loss of regiochemical integrity of the starting secondary tosylate
在作为催化剂的 Fe(acac)3/二膦和作为碱的 ArZnBr 存在下,具有 8-喹啉酰胺基团作为导向基团的烯烃、芳烃和杂芳烃与伯和仲烷基甲苯磺酸盐、甲磺酸盐和卤化物烷基化。该反应对烯烃底物立体特异性地进行,并且在不损失起始二级甲苯磺酸酯的区域化学完整性的情况下发生,但会损失手性中心的立体化学。
