gem-Dimethylcyclopropanation using triisopropylsulfoxonium tetrafluoroborate: Scope and limitations
A new nucleophilic isopropyl transfer reagent, triisopropylsulfoxonium tetrafluoroborate, has been prepared and evaluated. Thus, using this reagent and NaH in DMF, a range of electron deficient alkenes, including several chalcone analogues, alpha,beta-unsaturated ketones, dienones and quinones, plus alpha,beta-unsaturated esters, nitrile, sulfone and nitro examples, have been converted into the corresponding gem-dimethylcyclopropane compounds.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 538-58-9!
