Synthesis of the ketodifluoromethylene dipeptide isostere

10.1021/ja00173a066

The research pertains to the synthesis of the ketodifluoromethylene dipeptide isostere, a structure that closely resembles the putative tetrahedral intermediate in the proteolytic cleavage of peptide bonds, with the aim of inhibiting aspartic proteases such as human renin and HIV protease. The study presents a detailed methodology for synthesizing this isostere, which involves a series of chemical reactions including reduction, silylation, difluoromethylenation, and esterification, among others. Key chemicals used in the process include methyl (R)-1-phenylacetate, diisobutylaluminum hydride, CF2Br2, HMPT, NaOH, n-BuLi, 4-methylvaleryl chloride, LiN(TMS)2, (COCI)2, and NH3, among others.
