Using chiral phosphoramide ligand 2d-Zn (II) complex derived from (1R,2R)-1,2-diphenylethylenediamine as the catalyst, we have developed efficient catalytic asymmetric 1,2-addition/lactonization tandem reactions of diverse organozinc reagents with varied methyl 2-formylbenzoates for the construction of optically enriched 3-aryl or alkyl substituted phthalides, which are significant building blocks of many important chiral pharmaceuticals and natural products. The corresponding products could be afforded with good to excellent yields (up to 95%) and moderate to good enantioselectivities (up to 89%).

Abstract A chiral zinc complex of salen was found to be an efficient catalyst for the phenyl transfer of organozinc reagent to aromatic aldehydes and ketones. High enantioselectivities were obtained in reactions of both aromatic aldehydes and ketones (up to 97% and 92% ee, respectively).

Enantioenriched diaryl-, aryl heteroaryl-, and diheteroarylmethanols exhibit important biological and medicinal properties. One-pot catalytic asymmetric syntheses of these compounds beginning from readily available aryl bromides are introduced. Thus, lith
