A versatile one-pot synthesis of substituted isoindolinones from 2-furaldehydes, amines, 2-(phenylselanyl)acrylic acids, and isocyanides is described. The tandem process involves the Ugi four-component condensation, intramolecular Diels−Alder cycloaddition, and subsequent deselenization−aromatization promoted by BF3−OEt2. The procedure is general and efficient and the substrates are easily available
描述了一种由2-糠醛,胺,2-(苯基硒基)丙烯酸和异氰酸酯合成的取代异吲哚啉酮的通用一锅法。串联过程涉及Ugi四组分缩合,分子内Diels-Alder环加成以及随后由BF 3 -OEt 2促进的脱硒-芳构化。该过程是通用且有效的,并且衬底容易获得。
