摘要

Abstract The reaction of pyridinium or isoquinolinium N-ylides with methoxy-substituted ethylenes gave the corresponding indolizine and pyrrolo [2, 1-a] isoquinoline derivatives bearing acetyl, aroyl, cyano, ester group at the 1-position in one step. Pyrazolo [1, 5-a] pyridine, pyrazolo [1, 5-a] quinoline, and pyrazolo [5, 1-a] isoquinolines were also synthesized in good yields from the corresponding aromatic N-imines and ...
