Carbon-Phosphorus Bond Formation by Enantioselective Palladium-Catalyzed Allylation of Diphenylphosphine Oxide

The enantioselective Pd-catalyzed allylation of diaryl-substituted allylic carbonates and diphenylphosphine oxide was investigated. This method gave allylic diphenylphosphine oxides in yields up to 95 % with 97 % ee. Pd-catalyzed allylation of (E)-methyl

Copper-mediated cross-coupling of 1,1-dibromo-1-alkenes with dialkyl phosphites: A convenient synthesis of 1-alkenylphosphonates

An efficient and stereoselective procedure for the preparation of E-1-alkenylphosphonates by copper-mediated cross-coupling between 1,1-dibromo-1-alkenes and dialkyl phosphites is reported. The reaction allows for formal substitution of both bromine atoms

Transition metal-catalyzed intramolecular [4+2] cycloadditions: Mechanistic and synthetic investigations

The nickel-catalyzed intramolecular cycloaddition of dienes with unactivatable alkynes is found to proceed under mild conditions while the corresponding Diels-Alder cycloaddition of the same substrates either fails of occurs only under forcing conditions. The nickel-catalyzed cycloaddition is also shown to occur with retention of stereochemistry and is not significantly influenced by electronic effects. Finally, the catalyzed process is shown to be applicable to the synthesis of angularly substituted bicycles, including the CD ring systems of steroids and vitamin D.

Palladium-catalyzed preparation of dialkyl allylphosphonates. A new preparation of diethyl 2-oxoethylphosphonate

Palladium-catalyzed Michaelis-Arbuzov reaction of allyl acetates with trialkyl phosphites affords dialkyl allylphosphonates. Diethyl 2-oxoethylphosphonate is efficiently prepared by ozonization of diethyl allylphosphonate.
