Enantioselective synthesis of dihydrocoumarin derivatives by chiral scandium(iii)-complex catalyzed inverse-electron-demand hetero-Diels–Alder reaction1. Issue 18 (4th March 2015) - Hu, Haipeng
Abstract An asymmetric inverse-electron-demand hetero-Diels–Alder reaction between o-quinone methides and azlactones to generate potentially pharmacological active dihydrocoumarins has been achieved efficiently by using a chiral N, N′-dioxide–Sc(iii) complex as the catalyst.
