  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.

• Strain-Promoted Azide–Alkyne Cycloadditions of Benzocyclononynes

  Preliminary studies related to the design and development of new cycloalkyne reagents for metal-free click coupling are reported. Cydononynes are more stable than cyclooctynes, and the robust benzocyclononyne platform offers spontaneous reactivity toward azides at rates competitive with other azidophiles that have been employed for metal-free click coupling. Benzocyclononynes (e.g., 1) provide valuable insight into the design of new cycloalkynes for strain-promoted azide-alkyne cydoaddition (SPAAC) couplings for applications in which side reactions and decomposition of the reagent must be kept to a minimum.
