Synthesis of New 18-Membered Macrocycles by Cyclocondensation of Hydrazono Hydrazides of the Pyrazole Series
摘要
Abstract
New 18-membered nitrogen-containing bis-acylhydrazone macroheterocycles have been synthesized from N-phenacyl- and N-(alkoxycarbonylmethyl)pyrazoles bearing an alkoxycarbonyl or acetyl group at the ring carbon atom.
