Irradiation of phorone in methanolic solution gives, in addition to the two deconjugated isomers 2,6-dimethyl-hepta-1,5-dien-4-one and -1,6-dien-4-one, the cyclic photoproduct 5,6-dihydro-4-methoxy-2,2,6,6-tetramethyl-2H-pyran, which is of a novel type. Mechanistic implications are discussed.
在甲醇溶液中辐照佛尔酮,除了得到两个解共轭异构体2,6-二甲基-庚-1,5-dien-4-one和-1,6-dien-4-one之外,还得到了环状光产物5,6。 -二氢-4-甲氧基-2,2,6,6-四甲基-2 H-吡喃,是新型的。讨论了机械含义。
