Asymmetric synthesis of (S)-5 has been accomplished with an excellent enantiomeric excess by hydrogenation of raeemie 5 using ruthenium-BINAP-diamine-KOH system, followed by oxidation. Magnesium enolate of (2S)-2-methoxycyclohexanone [(S)-5] reacts with the 4-aeetoxyazetidinone 4 to give the key int
