Abstract

NEW MATERIAL:An azetidinone derivative of formula I: (R1 is protected amino group; R2 is 3W6C alkyl, 5W6C cycloalkyl or lower alkoxycarbonylmethyl group; R3 is H or OH-protecting group).
EXAMPLE: (3S)-1-(11-n-Butylaminocarbonyl-p-hydroxybenzyl)-3-t-butoxycarbonylamino-2-azetidinone.
USE: An intermediate for the synthesis of nocardin or its derivative.
PROCESS: An 3- amino-2-protected amino-propionic acid of formula II is reacted with a hydroxybenzaldehyde of formula III in the presence of an alkali in an inert solvent at 60W80°C, and neutralized with a mineral acid, then reacted with an isonitrile of formula IV to give the objective compound of formula I. Alternatively, the compounds of formulas II, III, and IV are reacted in an organic solvent, e.g. a lower aliphatic alcohol, with stirring.
