preparation of 4H‐1,3‐benzoxazin‐4‐ones by a domino carbonylation–cyclization process is developed. Readily available ortho‐iodophenols are subjected to palladium‐catalyzed carbonylative coupling with Mo(CO)6 and cyanamide, followed by a spontaneous, intramolecular cyclization to afford 4H‐1,3‐benzoxazin‐4‐ones in moderate to excellent yields. Furthermore, the scope of the reaction is extended to include
通过多米诺羰基化-环化过程,开发了一种温和方便的一步制备4 H -1,3-苯并恶嗪-4-酮的方法。现成的邻碘代苯酚与Mo(CO)6和氰胺进行钯催化的羰基偶合,然后自发地进行分子内环化,以中等至优异的产率得到4 H -1,3-苯并恶嗪-4-酮。此外,反应范围扩大到包括挑战性的邻溴酚。最后,为了强调所开发方法的多功能性,Mo(CO)6已成功地被广泛的CO释放试剂所取代,例如草酰氯,甲酸苯酯,9-甲基芴-9-羰基氯和甲酸,这使其成为合成4 H-苯并[ e ]的有吸引力的策略[ 1,3 ]恶嗪-4-酮。
Practical synthesis of indoles and benzofurans in water using a heterogeneous bimetallic catalyst
paper describes the preparation of indoles, azaindoles and benzofurans in pure water by using a new heterogeneous Pd-Cu/C catalyst through a cascade Sonogashira alkynylation-cyclization sequence. Details of the optimization studies and the substrate scope are discussed. This procedure allows the preparation of heterocycles with good yields and is tolerant to a wide variety of functional groups.

Vinyl chromium(0) Fischer carbenecomplexes were employed as the source of π‐allylic palladium species for catalytic [3+3] annulation under palladium catalysis. Mechanistically, this transformation is proposed to involve carbene migratory insertion and intramolecular Tsuji–Trost reaction as the key steps. Substituted six‐membered heterocyclic flavonones and quinolines are obtained, depending on the
