1,3-Dioxole derivatives were synthesized from copper(II)-catalyzed cyclization reactions of carbonyl ylides derived from 3-methylenebicyclo[2.2.1]heptan-2-one and dimethyl diazomalonate. The reaction mechanisms leading to all possible products have been extensively investigated by density functional theory. The generally accepted mechanism proposed by Doyle(12) for the carbene transformation reactions were applied to this system for the first time to shed light on the reaction mechanism and to understand the catalytic activity of Cu(acac)(2). Calculations have shown that the reaction mechanisms leading to different products greatly depend on the conformations of copper-stabilized carbonyl ylides, which are treated as reactants in our calculations. The conformational effects and donor-acceptor type stabilizations between the catalyst and the carbonyl ylide observed in the reactants and the transition state geometries seem to be the main reasons for the observed product selectivity. Our theoretical results are in good agreement with the experimental results, and the calculations successfully predict the experimental 75:25 product distribution.
