The scope of the Heck arylation of enol ethers with arenediazonium salts: a new approach to the synthesis of flavonoids

The scope of the Heck arylation of cyclic and acyclic enol ethers with arenediazonium salts was evaluated. Arylation of 2,3-dihydrofuran yielded 2-aryl-2,5-dihydrofurans as the major adducts (>99:1) except when using n-Bu4NHSO4 as ad

Epoxide opening reactions of aryl substituted dihydropyran oxides: Regio- And stereochemical studies directed towards deoxy-aryl-Cglycosides

2-Aryl-substituted tetrahydropyrans with 3,4- or 4,5-/ra;w-configured oxo substituents have been synthesized via ring-closing metathesis of allyl homoallyl ethers, epoxidation of the resulting dihydropyrans and opening of the epoxides with O-nucleophiles

Palladium (O) catalyzed insertion reactions to olefinic systems

Heck insertion reaction has been carried out on a number of acrylic acid and cinnamic acid derivatives with 4-bromoanisole in the presence of zerovalent palladium.Interestingly, two molecules of 4-bromoanisole couple to the olefinic double bond of 4-allyl-3-hydroxycoumarin.Insertion of 4-bromoanisole has also been extended to cyclic systems.The Heck insertion of 4-bromoanisole with 1,4-dihydro-2H-pyran in the presence of Pd(O) furnish 2-(4-anisyl)-5,6-dihydro-2H-pyran (12).
