α-Diaminoboryl carbanions, readily prepared from acetonitrile, stereoselectively convert 2-nitrobenzaldehydes into nitrophenyl (Z)-acrylonitriles. Subsequent reductive cyclization leads to a series of 2-aminoquinoline derivatives. The entire procedure is practically operated in a single flask.
α-二氨基硼基碳负离子可以通过简便的方法从乙腈中制备,具有立体选择性地将2-硝基苯甲醛转化为硝基苯(Z)-丙烯腈。随后进行还原环化反应,得到一系列2-氨基喹啉衍生物。整个过程几乎可以在一个烧瓶中完成。
