The synthesis of enantioenriched α-aryl-α'-allyl-γ-butyrolactones bearing vicinal tertiary and quaternary stereocenters through organocatalyzed asymmetric allylic alkylation is reported. The process demonstrated that weakly stabilized enolates der

International audience; The synthesis of cyclic, chiral α-trifluoromethylated N,O-acetals having a protected cis-diol moiety has been readily achieved in two steps from a known bis-Weinreb amide derived from l-tartaric acid. The reaction of O-acetyl

Condensation reactions of unprotected tetroses and pentoses with hydroxylamines afforded nitrones, which were easily converted to densely functionalized isoxazolidines in the presence of electron-poor alkenes. The 1,3-dipolar cycloaddition occurred w

International audience; The iridium-catalysed asymmetric allylic alkylation of γ-lactones produces an all-carbon quaternary stereocentre substituted by an allyl and a benzofuran. The resulting 1,5-hexadienes were found to be excellent substrates for

This paper describes the implementation of the pure absorption ALPESTRE processing of 2D homonuclear J-resolved NMR spectra. The method relies on the computation of the missing information at negative evolution times by means of backward linear predi

Photolabile protecting groups have proven their usefulness on many occasions. Their versions as linkers are however less attractive, as robustness and real orthogonality become critical issues. Safety-catch systems, where a preliminary activation pha

The synthesis of α,γ-substituted chiral γ-lactones was quickly achieved in a one pot sequential process. The procedure involves an enantioselective organocatalysed transfer of boronic acid to 5-hydroxyfuran-2(5H)-one, followed by an intramolecular
