The present strategy involves several reactions including cyclization/coupling/double C(sp3)-H functionalization in cascade manner. Wide range of 2-iodobenzamide substrates having different substituents as well as various propargyldicarbonyl and propargylsulfonyl aryl ketones are used to access variety of 3-hydroxy-3-furylisoindolinone derivatives in the present methodology.2. A facile copper-catalyzed three-component reaction for the synthesis of trisubstituted pyridines from 3-bromopropenals, benzoylacetonitriles, and ammonium acetate (NH4OAc) is developed. The Knoevenagel-type condensation of 3-bromopropenal with benzoylacetonitrile gives 2,4-dienone with strategically placed functional groups, which reacts with in situ generated ammonia to give the corresponding azatriene. A subsequent reaction sequence of 6π-azaelectrocyclization/aromatization produces a trisubstituted pyridine under the reaction conditions.3.Herein, we developed a simple and one pot method for the synthesis of isoindolo [1,2-b]quinazolin-12(10H)-one derivatives via copper catalyzed tandem reaction of N-(2-bromobenzyl)-2-iodobenzamide as substrate and copper cyanide. The procedure is easy, simple and the yields are good to excellent.雜環化學銅金屬催化6π-氮雜電環化雙環化反應克腦文蓋爾縮合反應喹唑啉衍生物3-羥基 -3-呋喃基異吲哚啉酮串聯反應烏爾曼型合環反應heterocyclic compoundCopper catalyzedUllmann type reaction6π-Azaelectrocyclization cyclizationDouble cyclizationKnoevenagel-type condensationQuinazolin derivatives3-Hydroxy-3-FurylisoindilinoneTandem cyclizationetd
