标 题 :Process for synthesis of N-acetylglycine
发明人：LIN JIANG-JEN; KNIFTON JOHN F; YEAKEY ERNEST L
权利人:TEXACO INC
摘要:An N-acetylglycine is manufactured by reacting paraformaldehyde with an acetamide and carbon monoxide in the present of a cobalt-containing catalyst promoted by a sulfoxide or dinitride compounds. The presence of sulfoxide or dinitrile ligands are essential for the high yield synthesis of N-acetylglycine and good cobalt recovery.

权利人:SEARLE & CO; MONSANTO CO
摘要:A synthesis is described for intermediates which are readily amenable to the large scale preparation of hydroxyethylurea-based chiral HIV protease inhibitors. The method includes forming a diastereoselective epoxide compound of formula (I) from a chiral alpha amino aldehyde and halomethyllithium as an organometallic methylene-adding reagent. In formula (I) R<1> is selected from alkyl, aryl, cycloalkyl, cycloalkylalkyl and arylalkyl, which are optionally substituted with a group selected from alkyl, halogen, NO2, OR<9> or SR<9>, where R<9> represents hydrogen or alkyl; and P<1> and P<2> independently are selected from amine protecting groups, including but not limited to, arylalkyl, substituted arylalkyl, cycloalkenylalkyl and substituted cycloalkenylalkyl, allyl, substituted allyl, acyl, alkoxycarbonyl, aralkoxycarbonyl and silyl.
