A Facile Synthesis of 1-Aryl-3-heteroaryl-1H-pyrazoloquinoxalines and Related Compounds with Antifungal Activity

The novel 1H-pyrazoloquinoxalines (flavazoles) 9-15 were synthesized from 3-methoxycarbonylmethylene-2-oxo-1,2,3,4-tetrahydroquinoxaline 6 via a convenient hydrazone synthesis, and these flavazoles were clarified to have the antifungal activity.

A New Synthesis of Novel 1-Aryl-3-heteroaryl-1H-pyrazoloquinoxalines via a Key Intermediate

The chlorination of the α-hydrazonoester 4 with phosphoryl chloride/pyridine gave 3--2-chloroquinoxaline 5, whose cyclization with 1,8-diazabicyclo-7-undecene afforded 3-methoxycarbonyl-1-(o-chlorop
