In a borrowing hydrogen cascade starting from racemic allylic alcs., one of the enantiomers could be kinetically resolved, while the other enantiomer could be purposely converted to various targeted products, including α,β-unsaturated ketones RC(O)C=CCH2R1 [R = Ph, 4-FC6H4, 2-naphthyl, etc.; R1 = (CH2)6, (CH2)7, OTBS], β-functionalized ketones R2C(O)CH2CH2R3 [R2 = 4-MeSC6H4, 4-t-BuC6H4, 4-MeOC6H4, etc.; R3 = OMe, OEt, morpholino, etc.] and γ-functionalized alcs. R4CH(OH)CH2CH2R5 [R4 = 4-ClC6H4, 4-FC6H4, 2-naphthyl, etc.; R5 = OMe, OBn, morpholino, etc.] was reported. By employing a robust Ru-catalyst, both kinetic resolution and asym. induction were achieved with remarkable levels of efficiency and enantioselectivity. D. functional theory (DFT) calculations suggested that corresponding catalyst-substrate π-π interactions were pivotal to realize the observed stereochem. diversity.
