It is found that the reaction of the selenonium salt 3b, an aldehyde, and potassium tert-butoxide can take place smoothly in ‘one-pot’ via the formation of selenonium ylide 4b, to give chiral trans-diaryl epoxides 5 in good yields with good diastereoselectivities and enantioselectivities.enChemistryYlideCamphorBiocatalysisEnantioselective synthesisAldehydeGreen chemistryOrganic chemistryIonic liquidSalt (chemistry)article
