Novel synthesis of 3-pyrrole substituted β-lactams via microwave-induced bismuth nitrate-catalyzed reaction
Highly stereoselective synthesis of 3-pyrrole substituted β-lactams is accomplished. The first step involves the synthesis of 3-phthalimido substituted β-lactams following Staudinger cycloaddition reaction of acid chloride equivalent with imines. Synthesi

Acetoxylation of β-lactams with lead(IV) acetate
1-(4-Methoxyphenyl)azetidin-2-ones 5a-5g were acetoxylated by lead(IV) acetate to afford the corresponding compounds 6a, 6b, 6c' and 6d-6g. In the d series elimination products 9 and 10 were also formed. Ring homologue 7a afforded the hydroxylated derivat
