摘要
Michael addition of hetero-nucleophiles to active vinylogous imine intermediates generated in situ from 3-(1-arylsulfonylalkyl)-7-azaindoles has been described. This new strategy provides a facile and efficient approach to valuable 3-alkyl substituted 7-azaindole derivatives containing heteroatoms in high yields. (C) 2015 Elsevier Ltd. All rights reserved.
