Abstract
NEW MATERIAL:Compounds of formula I' and formula I" [Ar is heteroaromatic group or group of formula p-Y>C6H4 (Y is F, OH, or protected OH); R is alkyl, aryl, etc.; X' is benzyloxy or azido; X" is OH or amino, provided that when x' is azido, Ar is not p-fluorophenyl].
EXAMPLE: 1-Phenyl-3-azido-4-(2'-furyl)azetidin-2-one.
USE: Intermediate for the preparation of useful animal growth promoter, etc.
PROCESS: Reaction of a Schiff base of formula II with a compound of formula III in a solvent such as benzene in the presence of a tert-amine such as triethylamine at -78W+100°C affords a compound of formula I', which is converted to a compound of formula I" by the hydrogenative decomposition in a solvent such as methanol, in the presence of a catalyst such as Pd black at room temp. W150°C.
