Asymmetric Organocatalytic Three-Component 1,3-Dipolar Cycloaddition: Control of Stereochemistry via a Chiral Brønsted Acid Activated Dipole
摘要:
A Bronsted acid catalyzed three-component asymmetric 1,3-dipolar addition reaction between aldehydes, amino esters, and dipolarophiles by a new bisphosphoric acid, derived from the linked BINOL, furnished multiply substituted pyrrolidines in high yield with excellent enantioselectivities under mild conditions.
