polysubstituted naphthalene derivatives via a pyrrolidine-mediated cascade Michael/Henry reaction was developed, in which easily prepared 2-(2-oxoethyl)benzaldehydes and nitroalkenes were employed as the starting materials. The reaction consists of four consecutive reactions that include a cascade Michael/Henry reaction, a dehydration reaction, and an aromatization reaction in one pot to afford synthetically
提出了一种通过吡咯烷介导的级联迈克尔/亨利反应合成多取代萘衍生物的新方法,该方法以易于制备的2-(2-氧代乙基)苯甲醛和硝基烯烃为原料。该反应由四个连续的反应组成,包括级联的迈克尔/亨利反应,脱水反应和在一个罐中的芳构化反应,从而以中等收率得到合成上重要的萘衍生物。
