A novel pyridine-based three-component condensation reaction: synthesis of highly substituted quinolizines
摘要:
Reaction of the zwitterions generated from pyridine or pyridine derivatives and dialkyl acetylenedicarboxy late with electron-deficient tetracyanoethylene lead to highly substituted quinolizines without using any catalyst or activation. (c) 2008 Published by Elsevier Ltd.
