Autor: Baptiste Leroux, Alexis Beaufils, Federico Banchini, Olivier Jackowski, Alejandro Perez-Luna, Fabrice Chemla, Marc Presset, Erwan Le Gall
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 20, Iss 1, Pp 2834-2839 (2024)
The use of alkylzinc bromides in the multicomponent Mannich reaction is described. Heteroleptic organozinc compounds were obtained in THF or 2-MeTHF by direct insertion of zinc dust into the C–Br bond of alkyl bromides. It was found that the presen

α-(Aminomethyl)acrylates as acceptors in radical–polar crossover 1,4-additions of dialkylzincs: insights into enolate formation and trapping
Autor: Angel Palillero-Cisneros, Paola G. Gordillo-Guerra, Fernando García-Alvarez, Olivier Jackowski, Franck Ferreira, Fabrice Chemla, Joel L. Terán, Alejandro Perez-Luna
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 19, Iss 1, Pp 1443-1451 (2023)
We demonstrate that α-(aminomethyl)acrylates are suitable acceptors for 1,4-additions of dialkylzincs in aerobic conditions. The air-promoted radical–polar crossover process involves the 1,4-addition of an alkyl radical followed by homolytic subst

Modular synthesis of 2-furyl carbinols from 3-benzyldimethylsilylfurfural platforms relying on oxygen-assisted C–Si bond functionalization
Autor: Sebastien Curpanen, Per Reichert, Gabriele Lupidi, Giovanni Poli, Julie Oble, Alejandro Perez-Luna
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 18, Iss 1, Pp 1256-1263 (2022)
3-Silylated furfurals, readily prepared in three steps from biomass-derived furfural and 5-methylfurfural, are converted into 3-silylated 2-furyl carbinols upon condensation with organomagnesium or organolithium reagents. The hydroxy unit of the carb

Modular access to substituted germoles by intramolecular germylzincation
Autor: Seydou Kassamba, Alejandro Perez-Luna, Franck Ferreira, Muriel Durandetti
Publikováno v: Chemical Communications. 58:3901-3904
Intramolecular alkyne germylzincation giving access to a wide range of germoles is achieved from triarylhydrogermanes in the presence of diethylzinc and AIBN as radical initiator. The reaction proceeds through activation of the Ge-H bond, leading to

tert-Butanesulfinamides as Nitrogen Nucleophiles in Carbon–Nitrogen Bond Forming Reactions
Autor: Johana Ramirez Hernandez, Fabrice Chemla, Franck Ferreira, Olivier Jackowski, Julie Oble, Alejandro Perez-Luna, Giovanni Poli
Publikováno v: CHIMIA, Vol 70, Iss 1-2 (2016)
The use of tert-butanesulfinamides as nitrogen nucleophiles in carbon–nitrogen bond forming reactions is reviewed. This field has grown in the shadow of the general interest in N-tert-butanesulfinyl imines for asymmetric synthesis and occupies now

C3–H Silylation of Furfural Derivatives: Direct Access to a Versatile Synthetic Platform Derived from Biomass
Autor: Sébastien Curpanen, Giovanni Poli, Alejandro Perez-Luna, Julie Oble
The sustainable production of industry-relevant chemicals, ranging from biofuels to pharmaceuticals, requires the development of efficient functionalization of biomass-derived building blocks, such as furan derivatives. Herein we report directed irid
