Pd(II) catalyzed reaction of N-carbomethoxy-2-alkynylanilines with allyl chlorides produces 2-alkyl-3-allyl-N-carbomethoxyindoles in the presence of oxirances; Aminopalladation of a N-carbomethoxy-2-alkynylaniline gives 3-(N-carbomethoxyindolyl)palladium intermediate, which regioselectively attacks on the γ position of chlorides to give 3-allyl-2-alkylindoles with concurrent regeneration of Pd(II)
在存在氧化剂的情况下,Pd(II)催化N-羰基甲氧基-2-炔基苯胺与烯丙基氯的反应生成2-烷基-3-烯丙基-N-羰基甲氧基吲哚;N-羰基甲氧基-2-炔基苯胺的氨基钯反应生成3-(N-羰基甲氧基吲哚基)钯中间体,该中间体选择性地攻击氯化物的γ位,得到3-烯丙基-2-烷基吲哚,同时再生Pd(II)催化剂。
