Palladium-catalyzed intramolecular oxidative alkylation of unactivated olefins
Pei, Tao,Wang, Xiang,Widenhoefer, Ross A.
, p. 648 - 649 (2003)
Reaction of 5,5-dimethyl-8-nonene-2,4-dione catalyzed by PdCl2(CH3CN)2 (5 mol %) in the presence of CuCl2 (2.5 equiv) at room temperature for 3 h formed 2-acetyl-3,6,6-trimethyl-2-cyclohexenone in 96% isolated yield. Palladium-catalyzed intramolecular oxidative alkylation tolerated a range of substitution and was applicable to the synthesis of spirobicyclic compounds and to the cyclization of ζ-alkenyl β-keto esters.

A new class of HCV NS3/4a protease inhibitors which contain a P2 to P4 macrocyclic constraint was designed using a molecular-modeling derived strategy. Exploration of the P2 heterocyclic region, the P2 to P4 linker, and the P1 side chain of this class of
CYCLISATION DE N-TOSYL OXIRANES-PROPYLAMINES: SYNTHESE D'HETEROCYCLES AZOTES.
Nuhrich, A.,Moulines, J.
, p. 3075 - 3088 (2007/10/02)
The cyclisation of N-tosyl-oxiranepropylamines is accomplished in aqueous basic medium and in anhydrous acid medium as well.In most cases, this reaction occurs by a regiospecific 5-exo-tet. ring closure and affords N-tosyl-2-pyrrolidinemethanols in high y
