标题 :Methods for the synthesis of α- hydroxy-β-amino acid and amide derivatives

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.

摘要:A process for the preparation of a 4-[3-carboxy-3-diazo-2-oxopropyl]azetidin-2-one of the formula ##STR1## comprising reacting a 4-acetoxy-2-azetininone of the formula ##STR2## with a compound of the formula ##STR3## in an inert solvent, in the presence of a base and of a silylating agent, in a one-pot process. n Many of the products are new. The products are useful in the synthesis of carbapenem antibiotics.
