摘要:The invention pertains to the synthesis of carbamate and urea compounds. In particular the invention is directed to the synthesis of carbamate and urea compounds which may be used in the production of compounds that are used to stabilize nitrocellulose. The method of the invention comprises preparing a carbamate or urea derivative comprising reacting an amine and a carbonate or carbamate in the presence of an ionic liquid.

摘要:Novel processes towards the synthesis of the antiviral valomaciclovir stearate in which an esterified guanine acetal is reduced to the corresponding alcohol, reacted with an activated amino acid and N-deprotected. The esterified guanine acetal is prepared from a 9-guanine derivative bearing an acyclic hydroxymethylbutylacetal. The processes are amendable to one-pot reactions.

摘要:The present invention provides unimolecular metal complexes having increased activity in the copolymerization of carbon dioxide and epoxides. Also provided are methods of using such metal complexes in the synthesis of polymers. According to one aspect, the present invention provides metal complexes comprising an activating species with co-catalytic activity tethered to a multidentate ligand that is coordinated to the active metal center of the complex.

摘要:Solid-phase synthesis of a peptide has a problem that a desired elongation reaction is prevented from proceeding by diketopiperazine and a 6-membered diamine skeleton compound formed when a protective group at the N-terminal is removed. The present inventors have found that when in production of a peptide by a solid-phase method, a peptide in which an amino group at the N-terminal is protected with a protective group having an Fmoc skeleton is treated in a specific solvent with a base having a pKa of 23 or more in acetonitrile as a conjugate acid, and a peptide chain is then elongated, it is possible to solve the problem described above.
