Abstract
Synthesis of amino beta-lactams is a crucial objective because of the medicinal properties associated with them and the products derived from of them. Stereocontrolled synthesis of phthalimido beta-lactams is performed and cis and trans-phthalimido beta-lactams are deprotected with ethylene diamine (and other reagents) to amino beta-lactams of diverse structures in excellent yield. This reaction is also conducted under solventless conditions to afford identical products.
