Patent number: 6603016Abstract: The invention relates to an improved process for the preparation of N-carboxyanhydrides by reaction of the corresponding amino acid or one of its salts with phosgene, diphosgene and/or triphosgene in a solvent medium, characterized in that at least a portion of the reaction is carried out under a pressure of less than 1000 mbar. The N-carboxyanhydrides are thus obtained with better yields and an improved purity.Type: GrantFiled: May 30, 2002Date of Patent: August 5, 2003Assignee: IsochemInventors: Fabrice Cornille, Marc Lebon

Patent number: 6562967Abstract: One aspect of the present invention relates to a method for the kinetic resolution of racemic and diastereomeric mixtures of chiral compounds. The critical elements of the method are: a non-racemic chiral tertiary-amine-containing catalyst; a racemic or diastereomeric mixture of a chiral substrate, e.g., a cyclic carbonate or cyclic carbamate; and a nucleophile, e.g., an alcohol, amine or thiol. A preferred embodiment of the present invention relates to a method for achieving the kinetic resolution of racemic and diastereomeric mixtures of derivatives of &agr;- and &bgr;-amino, hydroxy, and thio carboxylic acids. In certain embodiments, the methods of the present invention achieve dynamic kinetic resolution of a racemic or diastereomeric mixture of a substrate, i.e.Type: GrantFiled: November 5, 2001Date of Patent: May 13, 2003Assignee: Brandeis UniversityInventors: Li Deng, Jianfeng Hang, Liang Tang
