A straightforward chemoenzymatic synthesis of optically active trans-N,N-dialkylcyclopentane-1,2-diamines has been efficiently developed starting out from their analogous (±)-trans-2-(N,N-dialkylamino)cyclopentanols. The route involves the one-pot stereospecific transformation of the racemic amino alcohols into racemic diamines and a subsequent kinetic resolution by means of lipase-B from Candida
光学活性的一种直接的酶化学合成反式- Ñ,Ñ -dialkylcyclopentane -1,2-二胺已经有效地开发从它们的类似(±)起步-反式-2-(Ñ,ñ -二烷基氨基)cyclopentanols。该途径涉及外消旋氨基醇向外消旋二胺的一锅立体定向转化,以及随后借助于来自南极假丝酵母的脂肪酶-B催化的酰化反应的动力学拆分。仔细选择存在于二胺中的烷基取代基和应用于酶促反应的衍生化策略,可以轻松制备其他具有合成价值的光学活性物质反式-环戊烷-1,2-二胺衍生物。
