13 p, 1.6 MB Chiral synthesis of 3-amino-1-phenylbutane by a multi-enzymatic cascade system / Alcover Fortuny, Natàlia (Universitat Autònoma de Barcelona. Departament de Química) ; Álvaro, Gregorio (Universitat Autònoma de Barcelona. Departament de Química) ; Guillén, Marina (Universitat Autònoma de Barcelona. Departament de Química)
Asymmetric synthesis of chiral amines from prochiral ketones using transaminases is an attractive biocatalytic strategy. Nevertheless, it is hampered by its unfavorable thermodynamic equilibrium. In the present work, an insitu by-product removal strategy was applied for the synthesis of 3-amino-1-phenylbutane (3-APB) by coupling a transaminase with a pyruvate decarboxylase (PDC), which does not require the use of any expensive additional cofactor.
