  Copper(II)-Catalyzed Alkoxyhalogenation of Alkynyl Ureas and Amides as a Route to Haloalkylidene-Substituted Heterocycles

  摘要：

  A highly effective synthesis of haloalkylidene-substituted heterocycles by copper(II)-catalyzed cyclization of alkynyl ureas and secondary amides has been developed. The reaction, which involves a catalytic amount of CuCl2 and a stoichiometric amount of N-halosuccinimide, occurs selectively through an alkoxyhalogenation process. Alternatively, alkoxychlorination and alkoxybromination reactions can be performed working solely with stoichiometric CuCl, and CuBr2, respectively.

  Intramolecular Pd(II)-Catalyzed Cyclization of Propargylamides: Straightforward Synthesis of 5-Oxazolecarbaldehydes

  摘要：

  Direct synthesis of 2-substituted 5-oxazolecarbaldehydes was performed by intramolecular reaction of propargylamides through treatment with a catalytic amount of Pd(II) salts in the presence of a stoichiometric amount of reoxidant agent. The heterocyclization process was well-tolerated by a wide range of aryl, heteroaryl, and alkyl propargylamides. This protocol constitutes a valuable synthetic pathway to 5-oxazolecarbaldehydes, alternative to the formylation on oxazole rings, often unsatisfactory in term of regioselectivity and yields.

  The synthesis of potentially bioactive pyrroloazepinones based on the catalytic intramolecular cyclization of alkyne-substituted 1H-pyrrole-2-carboxylic acid amides has been developed. In the presence of either H2PtCl6·6H2O at 120 °C or AuCl3 at room temperature pyrrolo[3,2-c]azepin-4-ones are formed.

  stereoselective synthesis of conjugated dienes was realized for the first time via Pd‐catalyzed alkoxycarbonylation of easily available 1,3‐diynes. Key to success is the utilization of the specific ligand 1,1′‐ferrocenediyl‐bis(tert‐butyl(pyridin‐2‐yl)phosphine) (L1), which allows this novel transformation to proceed at room temperature. A range of 1,2,3,4‐tetrasubstituted conjugated dienes are obtained in

  共轭二烯的立体选择性合成是通过Pd催化的容易获得的1,3-二炔的烷氧基羰基化首次实现的。成功的关键是利用特定的配体1,1'-二茂铁基-双（叔丁基（吡啶-2-基）膦）（L1），该新颖的转化反应可在室温下进行。通过这种简单的方法，可以以高收率和选择性获得一系列1,2,3,4-四取代的共轭二烯。该协议的综合用途在构成天然产物rac-Cagayanin，rac-galbulin，rac-agastinol和大麻素G的几种重要中间体的简明合成中得到了展示。

  A general synthesis of 3-amidoindoles from easily available arylhydrazines and acylated propargylamines is described. In the presence of inexpensive Zn salts, alkyne amination and subsequent Fischer indole-cyclization took place in good yields with excellent regioselectivity providing an interesting scaffold for potentially bio-active compounds.

  An enantioselective (4+2) annulation of N-propargylamides and α,β-unsaturated imines/ketones has been accomplished under gold-complex and chiral quinine-derived squaramide synergetic catalysis, providing chiral tetrahydropyridines/dihydropyrans with high efficiency and selectivity. This method complements the (4+2) annulation of allene reagents via a formal cycloaddition on internal π-bond, which is
