実験手順

To a solution of 5.0 g of (3S,4S)-4-acetoxy-3-tritylamino-2-oxoazetidine in 100 ml of methanol are added under ice-cooling 1.6 ml of thiophenol and 15.5 ml of 1N aqueous solution of sodium hydroxide. The mixture is stirred for 20 minutes at the same temperature and for further 50 minutes at room temperature. The crystals separated out are collected by filtration to give 2.35 g of (3R,4R)-4-phenylthio-3-tritylamino-2-oxoazetidine (A). The filtrate is concentrated, and the residue is dissolved in ethyl acetate, washed with water, and concentrated. The residue is purified on a silica-gel column (ethyl acetate: n-hexane=1:1) to yield 2.65g of (3R,4S)-compound (B).
