Resumen:
A conceptually novel route for organocatalyst development is described. Biomass-derived chiral pyrrolidines were synthesized in excellent yields, regio and stereoselectivities via 1,3-dipolar cycloaddition reaction between levoglucosenone and azomethine ylides. An unprecedented isomerization led to a new family of pyrrolidines with an unusual relative stereochemistry. Preliminary results showed that these compounds are efficient and highly promising organocatalysts for iminium ion-based asymmetric Diels-Alder reactions.
