The process comprising the step of obtaining a mono- or dicyano substituted aniline compound of formula (IV) which is then converted to an anthranilic acid compound of formula (V) or an anthranilic amide compound of formula (Va). Further, the compound of formula (VI) can be optionally synthesized from compound of formula (IV or V or Va)
专利号:US-2008207950-A1 优先权日:2004-12-22 标 题:Enantioselective Synthesis of a Sterically Hindered Amine 发明人:BERENS ULRICH; MALAN CHRISTOPHE; KIRNER HANS JURG 权利人:CIBA SC HOLDING AG 摘要:Compounds of the formula (I) wherein R is phenyl, or phenyl substituted by Cl, Br, C 1 -C 4 alkyl or CF 3 ; R 1 is H or methyl or ethyl; R 2 is H or methyl or acyl; R 3 is H or methyl; R′ 4 is —CH 3 or â•?CH 2 ; may be obtained in high enantiopurity by hydrogenation of a compound of the formula (II) wherein R and R 3 are as in formula (I); A is acyl; and R 4 is —CH 3 or â•?CH 2 ; in the presence of a chiral Rhodium or Ruthenium catalyst. Residues R 1 as methyl or ethyl and/or R 2 as H or methyl may subsequently be introduced without racemization by deacylation and optional alkylation.
