摘要

Facile synthesis of 11H(2H)-4-oxopyrazolo3',4':6,5pyrido-3,2-aazulene-10-carboxylates (3) via a domino reaction of 3-(dimethyl-amino)-2-(2-methoxy-1-ethoxycarbonylazulen-3-oyl)acrylonitrile (1) with hydrazines (2) in moderate to good yields. This reaction provides a new procedure for synthesis of pyridinone-fused azulenes.
