Synthesis of E- and Z-substituted methylene-3,4-dihydro-2H-1-benzopyrans by regio- and stereocontrolled palladium-catalyzed intramolecular cyclization
Barberan, Olivier,Alami, Mouad,Brion, Jean-Daniel
, p. 2657 - 2659 (2001)
A stereocontrolled synthetic approach to E- and Z-substituted methylene-3,4-dihydro-2H-1-benzopyrans 5 is described from acyclic derivatives using as a key step the palladium-catalyzed intramolecular cyclic carbopalladation of iodoalkynes 4 followed by a
Facile construction of [6,6]-, [6,7]-, [6,8]-, and [6,9]ring-fused triazole frameworks by copper-catalyzed, tandem, one-pot, click and intramolecular arylation reactions: Elaboration to fused pentacyclic derivatives

A sequential copper-catalyzed, one-pot, click reaction-intramolecular direct arylation, which involves two mechanistically distinct reactions (atom-economical click reaction and direct arylation of 1,2,3-triazole), to generate [6,6]-, [6,7]-, [6,8]-, and
Diastereoselective intramolecular SmI2-H2O-amine mediated couplings
Dahlen, Anders,Petersson, Annika,Hilmersson, Goeran
, p. 2423 - 2426 (2007/10/03)
The effectiveness of SmI2-H2O-amine mixture for intramolecular couplings was discussed. Diastereoselectivities in the coupling of O-cyclohexanyliodophenol derivatives were provided into heterocycles. The amount of coupled product improved significantly as SmI2, the substrate and amine were premixed followed by a gradual addition of water.
Chromium(II)-Mediated Nickel(II)-Catalysed Cyclisations of (Iodoaryl)-Substituted Alkynes and Alkynals
Hodgson, David M.,Wells, Christopher
, p. 1601 - 1604 (2007/10/02)
The Chromium(II)-mediated Nickel(II)-catalysed cyclisations of (iodoaryl)-substituted alkynes 1, 2 and 7 and (iodoaryl)-substituted alkynals 9 and 10 to give the products 5, 6, 8, 11 and 12 respectively is described.
