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.

摘要:New chiral phosphinopyrrolidine compounds of the general formula: ##STR1## wherein R 1 is hydrogen or --COA 1 , --COOA 2 , --CONHA 3 , --SO 2 A 4 or --PO(A 5 ) 2 , A 1 , A 2 , A 3 , A 4 and A 5 each represents independently alkyl or aryl, R 2 is phenyl, di(lower-alkyl)aminophenyl, lower-alkoxyphenyl or 3,5-dimethyl-4-methoxyphenyl, and R 3 is phenyl, lower-alkylphenyl, di(lower-alkyl)aminophenyl, lower-alkoxyphenyl or 3,5-dimethyl-4-methoxyphenyl, with the proviso that R 2 and R 3 may not simultaneously by phenyl, p-di(lower-alkyl)-aminophenyl or p-lower-alkoxyphenyl, as well as the use of these compounds as ligand for a metal complex catalyst for asymmetric synthesis of optically active compounds. The new chiral phosphinopyrrolidine compounds are useful ligands which attain both of high optical yield and high reaction efficiency in catalytic asymmetric reduction.
