An efficient methodology for the synthesis of highly functionalized ellipticinium and ellipticine derivatives starting from the corresponding 2-bromocarbazoles via an AgOTf or CuI catalyzed electrophilic cyclization of 2-alkynyl-3-carbazolylaldimines is reported.
已报道了一种有效的方法,用于通过AgOTf或CuI催化的2-炔基-3-carbazolylaldimines的亲电环化反应,从相应的2-bromo咔唑开始合成高度官能化的椭圆形和玫瑰树碱衍生物。
