Abstract
Enantioselective reaction between 2,5-disubstituted pyrroles and diaryl-ketimines, generated in situ from isoindolinone-derived alcohols, is described. Pyrrole derivatives possessing congested tetrasubstituted stereogenic center in β-(C3) position are generally obtained in high yields and enantioselectivities. The transformation can be extended to 2-monosubstituted pyrroles, generating chiral α-(C5) functionalized pyrrole products. Control experiments were conducted In order to elucidate origins of low enantioselectivities observed in some of the products.
