Gallium(III)-promoted halocyclizations of 1,6-diynes

Cyclization of 1,6-diynes promoted by stoichiometric Ga(III) halides produces vinyl halides in good to excellent yields. Under acidic conditions, initially formed iodocyclization products undergo in situ Friedel-Crafts cyclizations, giving access to iodoi

Rhodium catalysed chemo- and stereoselective arylative and alkenylative cyclisation reactions of unsymmetric diynes containing a terminal alkyne moiety with organoboronic acids

Unsymmetric diynes possessing a terminal alkyne moiety reacted with organoboronic acids both chemo- and stereoselectively to afford arylated or alkenylated exocyclic dienes by catalysis from the [Rh(cod)OCH3] 2 complex. The use of a polar protic solvent, e.g. CH3OH is required for the success of the process under mild conditions.

Gold-Catalyzed Fluorination–Hydration: Synthesis of α-Fluorobenzofuranones from 2-Alkynylphenol Derivatives

The AuI-catalyzed fluorination–hydration of 2-alkynylphenol derivatives in the presence of Selectfluor [1-chloromethyl-4-fluoro-1,4-diazoniabicyclo-[2.2.2]octane bis(tetrafluoroborate)] has been developed. This method provides straightforward a

Iron(ii)-catalysed [2+2+2] cycloaddition for pyridine ring construction

We report a new, simple and air-stable iron(ii) complex pre-catalyst for the synthesis of substituted pyridines via a [2+2+2] cycloaddition between diynes and nitrile derivatives. The Royal Society of Chemistry 2014.

Catalytic enantioselective synthesis of chiral tetraphenylenes: Consecutive inter- and intramolecular cycloadditions of two triynes

Triynes having a phenylene-bridged 1,5-diyne moiety were transformed into substituted tetraphenylenes by the title sequence. A cationic Rh-ligand species catalyzed this highly enantioselective reaction. This protocol is a new and easy approach to the cons

Silylstannylation of highly functionalized acetylenes. Synthesis of precursors for annulations via radical or heck reactions

(Chemical Equation Presented) Pd-catalyzed silylstannylation of acetylenes tolerates a variety of reactive functional groups (aldehydes, nonterminal acetylenes, epoxides, activated and unactivated olefins), providing easy access to precursors that can be

Chemo- and regioselective crossed alkyne cyclotrimerisation of 1,6-diynes with terminal monoalkynes mediated by Grubbs' catalyst or Wilkinson's catalyst

A novel protocol for crossed alkyne cyclotrimerisations mediated by Grubbs' catalyst [RuCl2(=CHPh)(PCy3)2] allows the efficient synthesis of 4,6-substituted indolines with high regioselectivity, and it is complementary to
