标 题 :Formation of peptide bonds in the presence of isonitriles

摘要:Amino acids having masked amino groups react with amino acids having masked carboxyl groups to form peptide derivatives in good yields if the reaction medium contains an isonitrile. Isonitriles also are effective in causing condensation of amino acids having masked amino groups with compounds having active hydroxyl groups to the corresponding amino acid esters. The yields of the first-mentioned reaction are enhanced if the reaction mixture additionally contains one of the compounds having active hydroxyl groups. Both the peptide derivatives and the amino acid esters of the compounds having active hydroxyl groups are useful for peptide synthesis.

标 题:Process for the preparation of metachlorophenols
发明人：CORDIER GEORGES
权利人:RHONE POULENC SPEC CHIM
摘要:The invention relates to a process for the preparation of metachlorophenols. The process consists in selectively hydrodechlorinating, under the action of heat and in the liquid phase, polychlorophenols containing at least one chlorine atom in the meta position relative to the phenolic hydroxyl, by reacting these polychlorophenols with hydriodic acid in a quantity which is sufficient in relation to the chlorine atoms to be removed. The metachlorophenols obtained are organic synthesis intermediates.
