Diastereoselective synthesis of a key intermediate for the preparation of tricyclic β-lactam antibiotics

Takaji Matsumoto; Toshiyuki Murayama; Shigeru Mitsuhashi; Takashi Miura

Abstract Asymmetric synthesis of ( S )- 5 has been accomplished with an excellent enantiomeric excess by hydrogenation of racemic 5 using ruthenium-BINAP-diamine-KOH system, followed by oxidation. Magnesium enolate of (2 S )-2-methoxycyclohexanone [( S )- 5 ] reacts with the 4-acetoxyazetidinone 4 to give the key intermediate 3 with high yield and diastereoselectivity for the synthesis of sanfetrinem 1 .
