  Efficient dynamic kinetic resolution method for the synthesis of enantiopure 6-hydroxy- and 6-methoxy-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid

  摘要：

  Enantiomeric 6-hydroxy-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid (ee >99%), useful in the synthesis of modulators of nuclear receptors, including liver X receptor and its analogue 6-methoxy-1,2,3,4-tetrahydroisoquinoline-l-carboxylic acid (ee >99%), a source of the above enantiomer was synthesized through Candida antarctica lipase B-catalysed dynamic kinetic hydrolysis of the corresponding 1,2,3,4-tetrahydroisoquinoline-1-carboxylic esters (+/-)-4 center dot HCl and (+/-)-5. (R)-Selective hydrolysis in both organic solvents and an aqueous NH4OAc buffer at pH 8.5 was observed and the amino acids were obtained in good chemical yields (>87%). (C) 2016 Elsevier Ltd.
