Several substituted 3,3-dialkoxy-5-methoxycarbonylbicyclo[2.2.2]oct-5-en-2-ones underwent unusual oxidative decarbonylation to produce polysubstituted cyclohexenes upon direct irradiation and usual ODPM rearrangement under sensitized conditions. A plausible mechanism for the oxidative decarbonylation is also given.
几种取代的3,3-二烷氧基-5-甲氧基羰基双环[2.2.2]辛-5-en-2-酮在直接照射和敏化条件下的常规ODPM重排后经历不寻常的氧化脱羰作用,产生多取代的
环己烯。还给出了氧化脱羰的合理机制。
