THE REACTIONS OF o-QUINONE MONOIMIDES WITH SOME THIOPHENES AND FURANS

o-Quinone monoimides undergo inverse electron demand Diels-Alder reactions with thiophene, 2-alkylated thiophenes, 2- and 2,5-alkylated furans and benzofurans. 2,5-Dimethylthiophenes and 2-methylbenzothiophene, on the other hand interact with o-quinone

The Reactions of an o-Quinone Monoimide with Some Phenols

The o-quinone monoimide N-(2,4-dichloro-6-oxo-2,4-cyclohexadien-1-ylidene)-4-nitrobenzamide (1) reacts with 2,6-dimethoxy-, 2,6-dimethyl-, and 2,6-dichlorophenols (2a-c) to form N-(2,4-dichloro-6-hydroxyphenyl)-N-(3,5-dimethoxy-, 3,5-dimethyl-, 3,5-dichloro-4-hydroxy)-4-nitrobenzamides (3a-c), respectively.Oxidation of 3a by 1 and 3b by DDQ lead to N-aryl-p-iminoquinones 4a,b.Oxidative dimerizations by either C-C or C-O coupling occur when 1 is admixed with the sterically hindered 2,6-di-tert-butyl-, 2,4-di-tert-butyl-, 4-bromo-2,6-di-tert-butyl-, and 2,4,6-tri-tert-butylphenols.

The cycloaddition reactions of N-(2,4-dichloro-6-oxo-2,4-cyclohexadien-1-ylidene)-4-nitrobenzamide (3) and other o-quinone monoimides with electron-rich alkenes to give derivatives of 2,3-dihydro-4H-1,4-benzoxazine are described.Reaction of 3 with 2,3-dim
