Selective C3- or C5-Borylation of furfural derivatives: Enabling the synthesis of tri- and tetra-substituted furan Analogues

Autor: Alessia Mori, Mariana Isabel Crespo Monteiro, Filipa Siopa, Giovanni Poli, Julie Oble

Publikováno v: Tetrahedron Chem, Vol 11, Iss , Pp 100079- (2024)

A strategy of C3/C4 and C5/C4 bis-C–H functionalization of furfural and 5-hydroxymethylfurfural is presented. This task has been accomplished by the initial iridium-catalyzed C–H borylation of furfural, equipped with an appropriate imine function

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

Switchable selectivity in Pd-catalyzed [3 + 2] annulations of γ-oxy-2-cycloalkenones with 3-oxoglutarates: C–C/C–C vs C–C/O–C bond formation

Autor: Yang Liu, Julie Oble, Giovanni Poli

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 15, Iss 1, Pp 1107-1115 (2019)

Two complementary [3 + 2] annulation protocols between 3-oxoglutarates and cyclic γ-oxy-2-cycloalkenones, simply differing on the reaction temperature, are disclosed. These domino transformations allow C–C/O–C or C–C/C–C [3 + 2] annulations

Short Hydroacylation-Based Synthesis of Four Aryl-3-hydroxypropanones, Predictable Biomass-Derived C9 Platform Molecules

Autor: Simona Bassoli, Anett Schallmey, Julie Oble, Giovanni Poli, Alexandre Pradal

Publikováno v: Catalysis Research. :1-12

A two-step protocol for the synthesis of aryl-3-hydroxypropanones, which were regarded as lignin degradation products, was proposed herein. This protocol provided a more rapid and easier access to aryl-3-hydroxypropanones, and aryl-3-hydroxypropanone

Publikováno v: Nutrients, Vol 13, Iss 3, p 742 (2021)

Altered circulating levels of free fatty acids (FFAs), namely short chain fatty acids (SCFAs), medium chain fatty acids (MCFAs), and long chain fatty acids (LCFAs), are associated with metabolic, gastrointestinal, and malignant diseases. Hence, we co

Acid-mediated decarboxylative C–H coupling between arenes and O-allyl carbamates

Autor: Camilla Loro, Julie Oble, Francesca Foschi, Marta Papis, Egle M. Beccalli, Sabrina Giofrè, Giovanni Poli, Gianluigi Broggini

Publikováno v: Organic Chemistry Frontiers. 9:1711-1718

Treatment of O-allyl N-tosyl carbamates with arenes in the presence of Cu(OTf)2 or TMSOTf as promoters affords N-substituted 1-arylpropan-2-amines, 1,2-diarylpropanes, 1,1-diarylpropanes, or indanes, depending on the nature of the promoter.
