对映体纯的N-保护的顺-4-氨基苯并二氢吡喃-3-醇(合成新型HIV第二代蛋白酶抑制剂的关键前体),其反式异构体以及顺式和反式-1-氨基-1,2,3,4-四氢萘-2-醇,是有机合成中有用的手性催化剂,通过脂肪酶催化醇部分的动力学酰化,使用相应的底物,成功制备N-苄氧基羰基保护的衍生物。在所测试的生物催化剂中,洋葱假单胞菌和南极假丝酵母 B 脂肪酶在酰化过程中表现出优异的对映选择性,具体取决于所采用的反应条件。 (c) Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2006 年。
Enantiomerically pure N-protected cis-4-aminochroman-3-ol (key precursor in the synthesis of novel HIV second-generation protease inhibitors), its trans isomer and both cis- and trans-1-amino-1,2,3,4-tetrahydronaphthalen-2-ol, useful chiral catalysts in organic synthesis, have been successfully prepared through a lipase-catalyzed kinetic acylation of the alcohol moiety, employing as substrates the corresponding N-benzyloxycarbonyl-protected derivatives. Of the biocatalysts tested, Pseudomonas cepacea and Candida antarctica B lipases showed excellent enantioselectivities in the acylation processes depending on the reaction conditions employed.
