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

A Convenient Synthesis and Antifungal Activity of 1-Aryl-1H- and 1-Aryl-3-heteroaryl-1H-pyrazoloquinoxalines

Novel 1-aryl-1H- and 1-aryl-3-heteroaryl-1H-pyrazoloquinoxalines (flavazoles) 9a-c, 12, 13 were synthesized from 3-methyl-2-oxo-1,2-dihydroquinoxaline 5 and the 3-triazolylmethylene-2-oxo-1,2,3,4-tetrahydroquinoxaline 6, respectively, via a facile hydrazone synthesis using aryl diazonium salts.Some of the above flavazoles and their related compounds exhibited the antifungal activity in some extent.The above results are described.

A New Method for the Synthesis of Novel 1-Aryl-3-heteroaryl-1H-pyrazoloquinoxalines

The reaction of 3-(2,3-dihydro-4-methyl-3-thioxo-4H-1,2,4-triazol-5-ylmethylene)-2-oxo-1,2,3,4-tetrahydroquinoxaline 4 with o-chlorobenzenediazonium chloride gave 3--2-

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.
