Benzoquinone, reactions

Nan ya et al. (97) also reported the synthesis of isoindolediones by the reaction of miinchnones with 1,4-benzoquinones. Reactions with an unsymmetrical mtinchnone were not regioselective. Several groups have examined the reactions of miinchnones with unsaturated nitriles, including 2-chloroacrylonitrile (98), cinna-monitrile (78,99) and fumaronitrile (78) to give unexpected products in several cases. Eguchi and co-workers (100) smdied the cycloaddition of several mtinch-nones with electron-deficient trifluoromethylated olehns. Thus, miinchnones 176...
