Synthesis of C3 heteroatom-substituted azetidinones that display potent cholesterol absorption inhibitory activity

J Med Chem. 1998 Feb 26;41(5):752-9. doi: 10.1021/jm970676d.

Abstract

The C3 phenylpropyl side chain of N-phenylazetidinones related to SCH 56524 was modified by replacing the hydroxymethylene with various isoelectronic or isosteric groups. Modifications at the 3' position led to less-active compounds; however, modifications at the 1' position provided compounds with improved cholesterol absorption inhibitory activity. An enantioselective route for the synthesis of C3 1'-sulfur-substituted azetidinones and the development of structure-activity relationships for this series of compounds are presented.
