Reaction Steps

A solution of trans-3-(1-hydroxyethyl)-4-ethynyl-2-azetidinone (0.10 g) in ethanol (5 ml) is subjected to catalytic reduction with hydrogen gas in the presence of Lindlar catalyst (0.01 g). The reduction is continued until 14 ml of hydrogen gas has been absorbed. The catalyst is then filtered off and the filtrate is concentrated under reduced pressure to give 0.1 g of trans-3-(1-hydroxyethyl)-4-vinyl-2-azetidinone.
