A novel base-promoted cascade reaction of 2-methyl-3-(1-alkynyl)chromones to produce a 3C-xanthone-linked 3C-chromone scaffold has been developed. This tandem process involves multiple reactions such as Michael additions/cyclizations under mild conditions without a transition metal catalyst and inert atmosphere.
一种新型的碱促进的 2-甲基-3-(1-炔基)色酮的级联反应,生成了一个 3C-色酮连接的 3C-黄烷酮骨架。这个串联过程涉及到多种反应,如迈克尔加成/环化反应,在温和的条件下,不需要过渡金属催化剂和惰性气氛。
