AbstractChiral intermediates were prepared by biocatalytic processes for the chemical synthesis of three pharmaceutical drug candidates. These include (i) the synthesis of [(3R‐cis)‐3‐(acetyloxy)‐4‐phenyl‐2‐azetidinone2for the semi‐synthesis of paclitaxel (taxol)5, an anticancer compound; (ii) synthesis of chiral (exo,exo)‐7‐oxabicyclo [2.2.1] heptane‐2,3‐dimenthanol monoacetate ester9for the chemoenzymatic preparation of a thromboxane A2antagonist; (iii) the enzymatic synthesis ofS‐(−) 3‐benzylthio‐2‐methylpropanoic acid, a key chiral intermediate for the synthesis of antihypertensive drugs captopril10or zofenopril13.
摘要 通过生物催化过程制备了手性中间体,用于三种候选药物的化学合成。其中包括:(i) 合成[(3R-cis)-3-(乙酰氧基)-4-苯基-2-氮杂环丁酮2,用于抗癌化合物紫杉醇(taxol)5 的半合成;(ii) 合成手性(exo,exo)-7-氧杂双环[2.2.1]庚烷-2,3-二薄荷醇单乙酸酯9 的化学合成,用于血栓素 A2 拮抗剂的化学制备;(iii) 酶法合成S-(-) 3-苄硫基-2-甲基丙酸,这是合成抗高血压药物卡托普利10 或佐芬普利13 的关键手性中间体。
