A simple procedure has been developed for the synthesis of enantio- and diastereomerically pure carbohydrate analogues from glycerol and a variety of aldehydes in one pot using a four-enzyme cascade reaction. As a proof of concept of the usefulness of this enzymatic catalytic cascade the naturally occurring azasugarD-fagomine was synthesized. This work highlights the potential value of using enzymes in cascade reactions to selectively form complex products that by previous traditional organic chemistry could only be obtained via repeated isolation and purification of intermediates.
已经开发出一种简单的程序,用于通过四酶级联反应在一个反应瓶中从甘油和多种醛类合成对映体和非对映体纯的糖类类似物。作为这种酶催化级联反应有用性的概念验证,合成了天然存在的氨基糖D-fagomine。这项工作强调了在级联反应中使用酶的潜在价值,以选择性地形成复杂产物,而这些产物在以往传统有机化学中只能通过反复分离和纯化中间体获得。
