标题 :Bio-intermediates for use in the chemical synthesis of polyketides
发明人：SANTI DANIEL; ASHLEY GARY; MYLES DAVID C
摘要:The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKSâ€?) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediatesâ€?) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greaty simplified.

标题 :Methods for the synthesis of α- hydroxy-β-amino acid and amide derivatives
发明人：SEMPLE JOSEPH E; LEVY ODILE E
权利人:CORVAS INT INC
摘要:Methods for the synthesis of alpha-hydroxy-beta-amino acid and amide derivatives and alpha-ketoamide derivatives and novel derivatives made by these methods are provided. These methods involve reacting a N-terminally blocked (protected) aminoaldehyde with an isonitrile and a carboxylic acid to give an amino-alpha-acyloxy carboxamide. The acyloxy group may be removed to give the derivative. Alternatively the protecting group is removed and acyl shift occurs to give the derivative. These derivatives are useful in the synthesis of compounds such as peptidyl alpha-ketoamides and alpha-hydroxy-beta-carboxylic acid and amide derivatives. Certain of these compounds have been reported to have activity as inhibitors of proteases, such as serine proteases and cysteine proteases.
