Glycerol was used, for the first time, as a green and effective promoting medium for electrophilic activation of aldehydes, and with which, a catalyst-free system for some reactions that conventionally carried out using acid catalysts, such as synthesis of di(indolyl)methanes, 3,4,5,6,7,9-hexahydro-9-aryl-1H-xanthene-1,8(2H)-dione and 1-oxo-hexahydroxanthenes, was developed.
甘油首次被用作绿色有效的促进介质,用于醛的电亲和活化,并基于此开发了一种无催化剂的体系,用于一些传统上使用酸催化剂进行的反应,例如二(吲哚基)甲烷、3,4,5,6,7,9-六氢-9-芳基-1H-黄酮-1,8(2H)-二酮和1-氧基-六氢黄酮的合成。
