The challenging bioamination of hydrophobic substrates has been attained through the employment of a disperse system consisting of a combination of a low polarity solvent (e. g. isooctane or methyl‐tert‐butylether), a non‐ionic surfactant and a minimal amount of water. In these conditions, amine transaminases (ATA) were shown to efficiently carry out the reductive amination of variously substituted cyclohexanones, providing good conversions often coupled with a superior stereoselectivity if compared with the corresponding chemical reductive amination. An array of synthetically useful 4‐substituted aminocyclohexanes was consequentially synthesized through biocatalysis, analyzed and stereochemically characterized.

转氨酶在疏水性底物生物胺化分散体系中的应用

通过使用由低极性溶剂（例如异辛烷或甲基叔丁基醚），非离子表面活性剂和少量水组成的分散体系，可以实现疏水性底物具有挑战性的生物胺化作用。在这些条件下，胺转氨酶（ATA）被证明可以有效地进行各种取代的环己酮的还原胺化，与相应的化学还原胺化反应相比，可以提供良好的转化率，同时还具有出色的立体选择性。因此，通过生物催化合成，合成和表征了一系列有用的4-取代的氨基环己烷。
