我们开发了一种高效且环保的两步串联方法,用于在连续流动微反应器中由嗜热霉菌的脂酶 TL IM 催化合成含糖香豆素衍生物。与其他方法相比,该工作的显着特点包括绿色反应条件、停留时间短(50分钟)、催化剂更容易获得、生物催化反应过程高效且易于控制。这种使用连续流动技术的香豆素衍生物的两步串联合成是一个概念证明,它开启了酶促微反应器在香豆素衍生物生物转化中的应用。
FeCl3-catalyzed multicomponentreaction was developed for the facile synthesis of coumarin-3-carboxylic ester derivatives in a highly atom-economic and environmentally friendly way. Using simple and cheaply available salicylaldehydes, Meldrum's acid and alcohols as the starting materials, the method needs no extra additives and features wide substrate scope, good functional group tolerance and mild reaction conditions

coumarins and chromenes via conjugate addition represents a relatively unexplored and challenging task. To address this issue, herein, we report a new and general copper (I) catalyzed dearomative borylation process to synthesize boron-containing oxacycles. In this report, the borylation of coumarins, chromones, and chromenes comprising functional groups, such as esters, nitriles, carbonyls, and amides, has
