  Generation of Medium-Ring Cycloalkynes by Ring Expansion of Vinylogous Acyl Triflates

  摘要：

  Reductive cyclization of aryl and vinyl iodides tethered to vinylogous acyl trifiates (VATS) induces a ring-expanding fragmentation to provide cyclic alkynyl ketones, including strained nine-membered cycloalkynes, in fair to excellent yield. The tandem cyclization/C-C bond-cleavage is Initiated under carefully optimized conditions by halogen metal exchange in the presence of carbonyl and vinyl triflate functionality. A modified protocol for alkylation of 1,3-cyclohexanedione is described for preparing the relevant VAT substrates.

• Carbopalladation of Nitriles:  Synthesis of Benzocyclic Ketones and Cyclopentenones via Pd-Catalyzed Cyclization of ω-(2-Iodoaryl)alkanenitriles and Related Compounds

  An efficient procedure for the synthesis of 2,2-disubstituted benzocyclic ketones by intramolecular carbopalladation of nitriles has been developed. The cyclization of substituted 3-(2-iodoaryl)propanenitriles affords indanones in high yields. The reaction is compatible with a wide variety of functional groups. This methodology has been extended to the synthesis of tetralones and cyclopentenones.
