2-Spiroanellated 1,3-benzodioxoles from the reaction of 2,3-dihydro-1H-pyrrol-3-ones with tetrachloro-1,2-benzoquinone
Novel spiro[1,3-benzodioxole-2,2′-(2,3′-dihydro-1’H-pyrrol-3′-ones)] were obtained from 2-aminomethylene-2,3-dihydropyrrol-3(1H)-ones and tetrachloro- 1,2-benzoquinone in ethanol at room temperature. However, in addition, 3,4-dichloro-7-methoxy-5-(4-methoxyphenyl)-5,10-dihydrophenazine-1,2-dione was formed in the reaction of 1-(4-methoxyphenyl)-2-(4-methoxyphenylaminomethylene)-4,5 -diphenyl- 1,2-dihydropyrrol-3-one with tetrachloro-1,2-benzoquinone.
