摘要：

Anthranilic acid hydrazides were condensed with acetylene diesters, and the intermediate adduets were identified as aeylhydrazones of oxalacetic diester. These anthranilic hydrazones could be thermally cyclized to 2‐carboalkoxypyrazolo[5,1‐b] quinazolin‐9(1H)ones. Copyright © 1979 Journal of Heterocyclic Chemistry
