Photo-oxidation of 7-methylbenz[c]acridine in methanol. Identification of two primary photoproducts
Abstract
Irradiation at 365 nm of an oxygenated solution of 7-methylbenz[c]acridine in methanol yields a mixture of photoproducts of which two were shown by 1H and 13C n.m.r. to be trans-6-hydroxy-5-methoxy-7-methyl-5,6-dihydrobenz[c]acridine and trans-5-hydroxy-6-methoxy-7-methyl-5,6-dihydrobenz[c]-acridine.
