An efficient solution-phase parallel procedure to perform the structural diversification of some formyl aza-heterocycles employing supported organic bases (PS-BEMP, PS-TBD or Si-TBD) is described. The library synthesis is based on a consecutive alkylation-Knoevenagel functionalisation that employs alkyl halides, Michael acceptors, and malonic acid derivatives as diversity elements.
本文描述了一种高效的溶液相并行过程,利用负载型有机碱(PS-BEMP、PS-TBD或Si-TBD)对某些醛基氮杂环进行结构多样化的方法。该库合成基于连续的烷基化-Knoevenagel功能化反应,采用烷基卤、迈克尔受体和丙二酸衍生物作为多样性元素。
