A self-sufficient nicotinamide-dependent intramolecular bio-Tishchenko-type reaction was developed. The reaction is catalyzed by alcohol dehydrogenases and proceeds through formal intramolecular hydride transfer on dialdehydes to deliver lactones. Regioselectivity on [1,1′-biphenyl]-2,2′-dicarbaldehyde substrates could be controlled via the electronic properties of the substituents. Preparative scale
开发了一种自给自足的烟酰胺依赖性分子内生物-季申科型反应。该反应由醇脱氢酶催化,并通过在二醛上的正式分子内氢化物转移进行,以递送内酯。可以通过取代基的电子性质控制[1,1'-联苯] -2,2'-二甲醛的底物的区域选择性。制备规模的合成提供了对取代的二苯并[ c,e ] oxepin-5(7 H)-的访问。
