Synthesis of Some Novel Di- and Tri-β-lactams from Glycine

Annelation of the schiff bases (II) with appropriate β-lactam acids (I) results in the formation of di-β-lactams (III).Alternately IIIb can also be prepared as follows: Potassium carbethoxyacetonylglycinate (IV) on treatment with schiff base (IIb) using P

Studies on β-Lactams: Synthesis of Some Steroid-type Di-β-lactams

Schiff bases (1) on reaction with phenoxyacetyl chloride yield the β-lactam esters (2) which on further hydrolysis under mild basic conditions afford α-(2-oxo-1-azetidino)acetic acids (3).Reaction of the imines (4) with 3 using POCl3 and triethylamine fur
