| abstract | NEW MATERIAL:Optically active 4-alkoxyazetidin-2-one compound of formula I (R 1 is hydroxyl-protecting group; R 2 is H or amino-protecting group; R 3 is 1W4C aliphatic hydrocarbon group). n EXAMPLE: (3R,4R,5R)-3-[1-(t-butyldimethylsiloxy)ethyl-4-methoxy-azetidin-2-one. n USE: A synthetic intermediate for penem-type β-lactam antibiotic substance. The compound is characterized by the presence of alkoxy group at 4-site. n PREPARATION: The compound of formula I can be produced by reacting 3-[1-(t- butyldimethylsiloxy)ethyl]-4-acetoxyazetidin-2-one of formula II with sodium alcoholate as a base in an alkanol. n COPYRIGHT: (C)1988,JPO&Japio |
