The addition of FeCl3 and the use of DMSO as a solvent enabled the radical conjugate addition of a cyclic acetal and a cyclic amine to alkylidenemalonates using a reagent amount (12.5 equiv) of the radical precursors to give Michael addition pr

(Chemical Equation Presented) Cyclic and acyclic ether or acetal radicals were generated directly from ethers or acetals by the action of dimethylzinc-air, and their subsequent conjugate addition reaction with alkylidenemalonates afforded the corresponding conjugate adducts in reasonably high yields. The reaction with benzylidenemalonates bearing formyl and imino groups gave chemoselectively the conjugate addition products. The asymmetric reaction of bis(8-phenylmenthyl) benzylidenemalonate proceeded diastereoselectively to provide the adduct with 93:7 dr.
