Abstract: Enantioselective synthesis of the neurokinin 1 receptor antagonist (+)-L-733,060 has been achieved using Jacobsen’s hydrolytic kinetic resolution strategy. Intermediate tert-butyl (2S,3S)-3-hydroxy-2-phenylpiperidine-1-carboxylate has been synthesized with an overall yield of 10.25% and more than 98% ee via sequential reactions starting from cinnamyl alcohol and using Grubbs metathesis in the final stage.

An efficient diastereoselective approach to access trans-5-hydroxy-6-substituted 2-piperidinones skeleton has been developed through one-pot intramolecular tandem process of O-benzyl protected aldimine 11 with Grignard reagents. The diastereoselectivity of substitution at C-6 position of 2-piperidinone was controlled by α-benzyloxy group. In addition, the utility of this straightforward cascade process is demonstrated by the asymmetric syntheses of (+)-L-733, 060 (2) and its 2-substituted analogue 3, as well as (+)-CP-122721 (5).

An efficient synthesis of the 2,3-disubstituted piperidines (+)-L-733,060 and (2S,3S)-3-hydroxypipecolic acid (≥99% ee) in high optical purity from commercially available starting materials is described. The strategy involves a cobalt-catalyzed hydrolytic
