highly efficient strategy for obtaining a series of chiral 2,4-disubstituted thiazolone derivatives with excellent diastereo- and enantioselectivities through the creation of carbon- and nitrogen-substituted quaternary carbon stereocenters. With the chiral tertiary amine-thiourea catalyst developed by our group, the reactions could be performed smoothly at 1 mol-% catalyst loadings without any additive
