A base-promoted one-pot tandem reaction sequence has been developed to transform electron-deficient chromone-fused dienes 1 and 1,3-dicarbonyl compounds 2 to functionalized 2-hydroxybenzophenones 3 under mild conditions. This domino process, which involves multiple reactions, including Michael addition/cyclization/elimination, serves as an efficient, economic, and eco-friendly method for the construction
已经开发了碱促进的一锅串联反应序列,以在温和条件下将缺电子的色酮稠合二烯1和1,3-二羰基化合物2转变为功能化的2-羟基二苯甲酮3。这种多米诺骨牌工艺涉及多个反应,包括迈克尔加成/环化/消除反应,是一种高效,经济,环保的方法,可用于构建没有过渡金属催化剂和惰性气氛的各种2-羟基二苯甲酮支架。
