A highly efficient two-step chemoenzymatic synthesis of enantiopure structured ether lipids of the 1-O-alkyl-2,3-diacyl-sn-glycerol type has been developed. Chimyl, batyl and selachyl alcohols possessing pure saturated fatty acid (SFA) attached to the sn-3 position and pure EPA and DHA attached to the sn-2 position were obtained under full regiocontrol. This was offered by mild conditions and a highly
已经开发了1- O-烷基-2,3-二酰基-sn-甘油类型的对映纯结构化醚脂质的高效两步化学酶法合成。在完全区域控制下,获得了具有附接到sn -3位置的纯饱和脂肪酸(SFA)和附接到sn -2位置的纯EPA和DHA的Chimyl,batyl和selachyl醇。这是由温和条件和在室温下运行的高效脂肪酶提供的。高分辨率11 H NMR光谱法用于监测反应的进程,并通过跟踪参与这些反应的所有预期加合物来评估所涉及反应的完全区域控制。这扩展为针对C 2 -C 16的所有偶数SFA以及八个相应的EPA和DHA结构化的二酰基甘油醚(DAGE)产品(用于chimyl,batyl和selachyl醇)的八个单酰基中间加合物的重点文库的制备。总共72种化合物。
