Process for the preparation of 1,3-disubstituted-2-azetidinones from triazines

A process for preparing an azetidinone of the formula: STR1 which comprises reacting a C-unsubstituted methyleneamine of the formula: STR2 with R2 --CH2 COOH, its acid halide or anhydride, in the presence of boron trihalide and an organic base, wherein R1 is an organic residue bearing a carboxy group or its derivative and R2 is azido, substituted amino, halogen, acyloxy, alkoxy, aryloxy or aralkoxy.

2-Azetidinone compounds and processes for preparation thereof

This invention relates to new 2-azetidinone compounds, which have antimicrobial activities, and to processes for the preparation thereof, and more particularly, this invention provides new 2-azetidinone compounds, especially ones having various substituted carboxyalkyl radicals at the first position and having various groups at the fourth position of the azetidinone nucleus, which have antimicrobial activities against various pathogenic microorganisms and are useful as antibiotics in treatment for microbial infections in mammal including human being and animals.
