The domino reduction/imine formation/intramolecular aza‐Diels–Alder reaction delivers tetrahydrochromano[4,3‐b]quinolines with high exo‐E‐anti selectivity and yields up to 87 % by the reaction of nitrobenzenes and a 2‐(cinnamyloxy)benzaldehyde in aqueous citric acid by using iron as a reductant and montmorillonite K10 as a catalyst.
多米诺还原反应/亚胺形成反应/分子内氮杂Diels-Alder反应可提供具有高exo-E-抗选择性的四氢苯并[4,3- b ]喹啉,并通过硝基苯与2-(肉桂酰氧基)的反应收率高达87%通过使用铁作为还原剂和蒙脱土K10作为催化剂,在柠檬酸水溶液中形成苯甲醛。
