PREPARATION OF EPSILON-CAPROLACTAM FROM (Z)-6,7-DIHYDRO-1H-AZEPIN-2(5H)-ONE

摘要

The invention relates to a method for preparing e-caprolactam comprising reducing the carbon-carbon double bond of (Z)-6,7-dihydro-1H-azepin-2(5H)-one, wherein the reduction is catalysed by a biocatalyst.The invention further relates to a novel host cell comprising a biocatalyst capable of catalysing said reduction and to a novel polynucleotide encoding a biocatalyst capable of catalysing said reduction.
