摘要:
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 β-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
摘要:
The present invention is a process for the preparation of diphenylazetidinone derivatives of the formula (I) or forms thereof comprising the substituents X, R1 and/or R2 as defined herein. More specifically, the invention comprises methods for the preparation of these compounds by cyclization of certain □-amino carboxamides or □-amino carboxylic esters. These diphenylazetidinone compounds are useful in the treatment of high blood serum cholesterol levels and the maintenance of the reduced cholesterol levels achieved thereby.
