  • Title: Aminocatalytic asymmetric inverse-electron-demand aza-Diels-Alder reaction of N-Ts-1-aza-1,3-butadienes based on coumarin cores.
    Author: Li JL, Zhou SL, Han B, Wu L, Chen YC.
    Journal: Chem Commun (Camb); 2010 Apr 21; 46(15):2665-7. PubMed ID: 20449332.
    Abstract:
    The asymmetric inverse-electron-demand aza-Diels-Alder reaction of N-Ts-1-aza-1,3-butadienes derived from 3-argiocarbonylcoumarins and acetaldehyde has been developed using chiral secondary aminocatalysis, giving tricyclic chroman-2-one derivatives in high enantioselectivities (up to 95% ee).
