The use of small rotors capable of very fast magic-angle spinning (MAS) in conjunction with proton dilution by perdeuteration and partial reprotonation at exchangeable sites has enabled the acquisition of resolved, proton detected, solid-state NMR spectra ...
As a result of detailed mechanistic and kinetic studies, we have proposed that PdX2-catalyzed oxidative coupling of o-alkynylanilines 1 with terminal alkynes 2 under aerobic conditions is initiated by aminopalladation of 1 followed by ligand exchange of th ...
Cyclopropanes fused to pyrrolidines are important structural features found in a number of marketed drugs and development candidates. Typically, their synthesis involves the cyclopropanation of a dihydropyrrole precursor. Reported herein is a complementary ...
In the presence of Zn(OTf)2, the three-component domino reaction of N formylmethyl-substituted tertiary amides and enamides with amines and isocyanides in acetonitrile at room temperature produced functionalized imidazoliniums in good to excellent yields. ...
My PhD work started with the development of a racemic access to trigonoliimine B, an hexacyclic alkaloid isolated in 2010. After having explored different strategies, we reported a 7-step synthesis of this natural product. This synthesis features a challen ...
Acousto-optical coherence tomography (AOCT) is a variant of acousto-optic imaging (also called ultrasound modulated optical tomography) that makes possible to get resolution along the ultrasound propagation axis z. We present here AOCT experimental results ...
Be like Mike: The title reaction in the presence of the catalyst 1 afforded Michael adducts in excellent yields and enantioselectivities. The adducts were readily converted into alpha,alpha’-disubstituted alpha-amino acids. The enantioselective total synth ...
The base-catalyzed intramolecular hydroamination of 1-ethylaminocyclohexa-2,5-dienes is described. The transformation proceeds through isomerization of the cyclohexa-1,4-dienyl fragment into the corresponding conjugated 1,3-diene prior to the hydroaminatio ...
(1R)-Normetanephrine is the natural stereoisomeric substrate for sulfotransferase 1A3 (SULT1A3)-catalyzed sulfonation. Nothing appears known on the enantioselectivity of the reaction despite its potential significance in the metabolism of adrenergic amines ...
The iron(III) chloride-multicatalyzed dioxygenation of enamides with TEMPO in the presence of alcohols has been developed. This multicomponent domino process affords efficient new strategies for the synthesis of alpha-oxy-N-acylhemi-aminals or alpha-oxyimi ...
