The present invention relates to a method for preparing an optically active 4-hydroxy-1,2,3,4-tetrahydroquinoline compound [I], which comprises the steps of:
treating a racemic 4-hydroxy-1,2,3,4-tetrahydroquinoline compound represented by general formula [I]:
[wherein R
1
represents a hydrogen atom or a protecting group for amino group.]
with an enzyme having an ability of selectively or preferentially acylating one enantiomer of the racemic compound [I] in the presence of an acyl donor; and
if necessary, subjecting the reaction product to solvolysis.
本发明涉及一种制备光学活性的4-羟基-1,2,3,4-四氢喹啉化合物[I]的方法,其包括以下步骤:在酰基供体存在下,用具有选择性或优先酰化外消旋化合物[I]的一对映体的能力的酶处理由通式[I]表示的外消旋4-羟基-1,2,3,4-四氢喹啉化合物:[其中R1表示氢原子或氨基保护基];如有必要,将反应产物进行溶剂解。
