摘要:
Epoxide based cysteine protease inhibitors containing peptide derivatives and methods for synthesizing them in sold phase are disclosed. Preferably, an epoxy succinyl "warhead" (for binding to the enzyme) is prepared, having two amino acid residues or residue-like structures on either side. Natural and non-natural amino acids may be used. The present process may be carried out entirely on a solid support, with the proviso that a dipeptide like group is prepared prior to coupling to one side of the supported complex. The method lends itself to more efficient inhibitor synthesis, and may be employed with mixtures of peptide compounds, and various modifications of epoxides to create diverse libraries of inhibitors.

摘要:
The present invention relates to a process for stereoselective or regioselective chemical synthesis which generally comprises reacting a nucleophile, selected from the group consisting of water, alcohols, carboxylic acids, and thiols, and a racemic or diastereomeric mixture of a cyclic substrate in the presence of a non-racemic, chiral catalyst to effect a kinetic resolution of the cyclic substrate. The present invention also relates to hydrolytic kinetic resolutions of racemic and diastereomeric mixtures of epoxides.
