Aryl sulfoxides via palladium-catalyzed arylation of sulfenate anions.
[Structure: see text] Palladium-catalyzed arylation of sulfenate anions generated from beta-sulfinyl esters can take place under biphasic conditions. This hitherto unknown reaction provides a simple,Expand

New strategy for the construction of a monotetrahydrofuran ring in Annonaceous acetogenin based on a ruthenium ring-closing metathesis: application to the synthesis of Solamin.
An original convergent total synthesis of Solamin (type A annonaceous acetogenin) was achieved. The central THF core was obtained by means of a ring-closing metathesis (RCM) reaction using aExpand

Enantioselective synthesis of aryl sulfoxides via palladium-catalyzed arylation of sulfenate anions.
Arylation of various sulfenate anions generated from beta-sulfinyl esters by retro-Michael reaction in the presence of palladium(0) and enantiopure ligands gave the corresponding aryl sulfoxides inExpand

Aryl sulfoxides from allyl sulfoxides via [2,3]-sigmatropic rearrangement and domino Pd-catalyzed generation/arylation of sulfenate anions.
Allylic sulfoxides, via [2,3]-sigmatropic rearrangement and oxidative addition of the resulting allylic sulfenate esters to Pd(0), are found to be excellent precursors of sulfenate anions. ThisExpand

Allylic alkylation and ring-closing metathesis in sequence: a successful cohabitation of Pd and Ru.
An allylic alkylation/ring-closing metathesis domino catalytic process, wherein a palladium and a ruthenium catalyst are concomitantly present in the reaction mixture from the outset of the reaction,Expand

New picropodophyllin analogs via palladium-catalyzed allylic alkylation-Hiyama cross-coupling sequences.
Unsaturated malonyl esters underwent Pd-catalyzed intramolecular allylic alkylation to give 4-vinyl-substituted gamma-lactones. In contrast to the formerly studied cyclization of malonamides, thisExpand

Cavitand supported tetraphosphine: cyclodextrin offers a useful platform for Suzuki-Miyaura cross-coupling.
The cyclodextrin-tetraphosphine hybrid coined α-Cytep allows turnover numbers up to 340,000,000,000 and turnover frequencies up to 1,000,000,000 h(-1) to be reached in Suzuki-Miyaura reactions. TheseExpand
