Hayashi, Yujiro; Samanta, Sampak; Gotoh, Hiroaki; Ishikawa, Hayato published the artcile< Asymmetric Diels-Alder reactions of α,β-unsaturated aldehydes catalyzed by a diarylprolinol silyl ether salt in the presence of water>, Electric Literature of 3893-18-3, the main research area is unsaturated aldehyde cyclopentadiene diarylprolinol catalyst water Diels Alder; norbornene derivative stereoselective preparation; conjugated diene unsaturated aldehyde diarylprolinol catalyst water Diels Alder; cyclohexene carboxaldehyde derivative stereoselective preparation.
The title reaction predominantly affords the exo isomer with excellent enantioselectivity. The synthesis can be carried out without organic solvents and provides the products by distillation Water increases the rate and enantioselectivity of the reaction.
