structural motifs such as C-2 and C-3 substitutions (alkyl or aryl), cis/trans relative stereochemistry and functionalization of the aromatic ring (fluoro, methyl or methoxy groups) have been efficiently prepared through Fischer indolization and subsequent diastereoselective reduction of the unprotected indoles. Combination of Candida antarctica lipase type A and allyl 3-methoxyphenyl carbonate has been
通过Fischer吲哚化已有效制备了外消旋二氢吲哚,包括各种结构基序,例如C-2和C-3取代(烷基或芳基),顺/反相对立体化学和芳香环(氟,甲基或甲氧基)的官能化以及随后的非保护吲哚的非对映选择性还原。的组合南极假丝酵母脂肪酶A型和烯丙基3-甲氧基苯基碳酸酯已经被鉴定为对他们的动力学拆分最好串联,观察对于大多数所测试的二氢吲哚的优良stereodiscriminations。
