A process for producing an optically active form of a compound of formula (I)
wherein R₁ represents hydrogen or a hydrocarbon group that may be substituted; R₂ and R₃ independently represent hydrogen, a hydrocarbon group that may be substituted, or a heteroaromatic group that may be substituted; X' represents a substituent comprising an esterified carboxyl group or an acylated hydroxyl group; ring A represents a benzene ring that may be substituted or a heteroaromatic ring that may be substituted; ring J' represents a 7- or 8-membered heterocyclic ring containing at most 3 hetero-atoms as ring-constituent members, which may have a further substituent or substituents in addition to R₁, R₂, R₃ and X', and C* denotes a chiral carbon atom or a salt thereof, which comprises subjecting the racemic compound of the formula (I) or a salt thereof, or alternatively a racemic starting compound for synthesizing the compound of the formula (I) to enzymatically enantioselective hydrolysis to provide an optically active form thereof.
一种生产式(I)化合物光学活性形式的工艺
其中 R₁ 代表氢或可被取代的烃基;R₂ 和 R₃ 独立地代表氢、可被取代的烃基或可被取代的杂芳基;X'代表由酯化羧基或酰化羟基组成的取代基;环 A 代表可被取代的苯环或可被取代的杂芳环;环 J'代表最多含有 3 个杂原子作为环取代基的 7 元或 8 元杂环,除了 R₁、 R₂、R₃ 和 X'之外,还可以有一个或多个取代基,C* 表示手性碳原子或其盐、其中包括将式(I)的外消旋化合物或其盐,或合成式(I)化合物的外消旋起始化合物进行酶法对映选择性水解,以提供其光学活性形式。
