摘要
An asymmetric synthesis of neurokinin substance P receptor antagonist (+)-L-733,060 starting from enantiomerically pure ethyl (R)-(+)-2,3-epoxypropanoate (ethyl glycidate) is described The synthesis relies on a diastereoselective reductive animation, regioselective intramolecular epoxide opening, and in situ cyclization as the key steps.
