Abstract
A procedure for preparing 2-azetidinone compounds of the formula **(See formula)** where R1 is amino, substituted amino, substituted hydroxyl; azido or halogen, R2 is hydrogen, hydrozimethyl, aralkoxyiminomethyl, aryl, aralkenyl, formyl, carboxyl or a nucleophilic residue, and R3 is an organic residue bearing carboxyl or its derivative, which comprises reacting the compound of formula: (CH2 = N-R3) n with a compound of the formula: r1'CH2cooh or its reactive derivative, in the presence of Lewis acid and base, to give a compound of the formula: **(See formula)** being, in the above formulas, R1'protected amino, substituted hydroxyl, azido or halogen, n an integer from one to three, and R3 as defined above.
