The silver(I)-catalyzed reaction of ortho-alkynylbenzaldoximes with propargylic alcohols represents a new strategy for the divergent one-pot synthesis of 2-(isoquinolin-1-yl) prop-2-en-1-ones via tandem 6-endo-cyclization, 1,3-dipolar cycloaddition, and intramolecular dehydrative opening of the 2,3-dihydroisoxazole ring. This synthetic protocol tolerates a wide variety of ortho-alkynylbenzaldoximes and propargylic alcohols and affords the corresponding products in excellent yields.

A new and convenient strategy for the synthesis of functionalized tropone derivatives based on the gold-catalyzed oxidative ring expansion of alkynyl quinols has been developed. The reaction proceeds via gold-catalyzed highly regioselective oxidation foll

The synthesis of 9,10-bis(phenylethynyl)anthracene has been examined in detail prior to the synthesis of a series of phenylethynyl substituted aromatic compounds which are of interest as fluorescent materials for peroxyoxalate chemiluminescence.Reductions of the 9,10-bis(phenylethynyl)-9,10-dihydroanthracene-9,10-diol precursor by stannous chloride and by sodium hypophosphite-potassium iodide both gave a series of byproducts, in addition to 9,10-bis(phenylethynyl)anthracene.The formation of these compounds is interpreted in terms of a free-radical process.The interaction of 10-hydroxy-10-(phenylethynyl)anthrone with both the reducing systems has been rationalized and the reaction with concentrated sulfuric acid reinterpreted.
