Oxidative free-radical cyclizations of γ,γ-(bis)allylic acetoacetates demonstrate that 1,1-disubstituted double bonds are much more reactive than mono- or chloroalkyl-substituted double bonds. The product isolated suggests that bicyclo[3.2.1]octanes 25, 33 and 36 are formed from boat cyclohexyl radical 42 and tandem cyclization products 30, 37 and 38 are obtained from boat cyclohexyl radical 41.
γ,γ-(双)烯丙基乙酰乙酸酯的氧化自由基环化表明1,1-二取代的双键比单或氯烷基取代的双键更具反应性。分离的产物表明,双环[3.2.1]辛烷25,33和36是从船环己基形成42个串联环化产物30,37和38是从船环己基得到41。
