The lipase-catalyzed kinetic resolution of trans- and cis-2-azidocycloalkanols and the preparation of enantiomerically pure trans- and cis-2-aminocycloalkanols are described. Four kinds of lipases were screened for the acetylation of trans- and cis-2-azidocycloalkanols. Among them, Pseudomonas sp. lipases (lipase PS and lipase AK, Amamo Pharmaceutical Co.) showed the highest enantioselectivity. These
描述了脂肪酶催化的反式和顺式-2-叠氮基环烷醇的动力学拆分以及对映体纯的反式和顺式-2-氨基环烷醇的制备。筛选了四种脂肪酶,用于反式和顺式-2-叠氮基环烷醇的乙酰化。其中,假单胞菌属sp。脂肪酶(脂肪酶PS和脂肪酶AK,Amomo Pharmaceutical Co.)显示出最高的对映选择性。使用(S)-TBMB羧酸[(S)-2-叔丁基-2-甲基- 1,3-苯并二恶唑-4-羧酸]作为手性转化试剂。CD分析的结果证明N,O-双-(S)-TBMB羧化的顺-2-氨基环烷醇主要采用N-赤道构象。
