Lewis acid-catalyzed Wolff cyclocondensation in the synthesis of (1H-1,2,3-triazolyl)furoxans
ARKIVOC(2017)
摘要
Novel regioselective approach to the synthesis of (1H-1,2,3-triazol-1-yl) furoxans based on Lewis acid-catalyzed Wolff cyclocondensation of aminofuroxans with diazo-beta-dicarbonyl compounds has been developed. This approach allows to involve aminofuroxans as substrates which are very weak nucleophiles and usually do not participate in reactions with common electrophiles.
