Design of small molecule ketoamide-based inhibitors of cathepsin K
摘要:
A novel series of ketoamide-based inhibitors of cathepsin K has been identified. Modifications to p(2) and p(3) elements were crucial to enhancing inhibitory activity. Although not optimized, a selected inhibitor was effective in attenuating type 1 collagen hydrolysis in a surrogate assay of bone resorption. (C) 2003 Elsevier Ltd. All rights reserved.

Diamine-mediated α-deprotonation of O-alkyl carbamates or benzoates with alkyllithium reagents, trapping of the carbanion with organoboroncompounds, and 1,2-metalate rearrangement of the resulting boronate complex are the primary steps by which organoboroncompounds can be stereoselectively homologated. Although the final step can be easily monitored by 11B NMR spectroscopy, the first two steps, which
Stereospecific Reaction of α-Carbamoyloxy-2-alkenylboronates and α-Carbamoyloxy-alkylboronates with Grignard Reagents - Synthesis of Highly Enantioenriched Secondary Alcohols

Highly enantioenriched secondary alcohols were synthesized by treatment of α-carbamoyloxy-2-alkenylboronates and α-carbamoyloxy-alkylboronates with Grignard reagents. An intermediary boronate complex was transformed stereospecifically to the corresponding secondary 2-alkenyl- and alkylboronates by migration of an introduced residue. Oxidative workup furnished the enantioenriched secondary alcohols.
