The effect of silyl substituents in diphenylprolinol silyl ether catalysts was investigated. Mechanistically, reactions catalyzed by diphenylprolinol silyl ether can be categorized into three types: two that involve an iminium ion intermediate, such as fo

An MT-sulfone group was converted to a trifluoromethyl group by treatment with IF5 after an alkylation reaction. Therefore, an MT-sulfone anion can be used as a trifluoromethyl anion equivalent. The formal asymmetric Michael-addition of a trifl
Formal highly enantioselective organocatalytic addition of alkyl anions to α,β-unsaturated aldehydes: Application to the synthesis of isotope-enantiomers

A practical and powerful methodology that constitutes an organocatalytic alternative for organometallic 1,4-additions was developed. In a vial, bis(phenylsulfonyl)methane and catalyst V were added to toluene. Next, unsaturated aldehyde 1a was added and th

An indirect organocatalytic method for the β-methylation of α,β-unsaturated aldehydes that involves the addition of bis(arylsulfonyl)methane catalyzed by prolinol derivatives and further elimination of the chameleonic sulfonyl groups is presented. The Roy
