Zusammenfassung:	The present invention is directed to the preparation of novel compounds useful in the treatment of hyperlipidemia, arteriosclerosis, hypercholesterolemia, and other related metabolic disorders. More specifically, the present invention is a novel process for the preparation of 1,4-diphenylazetidinone derivatives from beta-substituted amino amides which are protected in the presence of silylating agents and at least one cyclization catalyst whose structural formula is represented by one of the general formula: Wherein the various R-groups are defined herein
