Allylboration of Ketones Catalyzed by BINOL Derivatives: Which Species Are Involved Depending on Substrate Reactivity? Open
Allylboration reactions of ketones catalyzed by BINOL derivatives can exhibit highly variable stereochemical courses depending on the nature and reactivity of the ketone substrate. In this Article, we put into perspective the relationship …
Synthesis, structural characterization, and chiroptical properties of planarly and axially chiral boranils Open
2‐Amino[2.2]paracyclophane reacts with salicylaldehyde or 2‐hydroxyacetophenone to yield imines that then give access to a new series of boranils ( 8b–d ) upon complexation with BF 2 . These novel boron‐containing compounds display both pl…

Microwave‐Assisted 1,3‐Dioxa‐[3,3]‐Sigmatropic Rearrangement of Substituted Allylic Carbamates: Application to the Synthesis of Novel 1,3‐Oxazine‐2,4‐dione Derivatives Open
In a first instance, the effect of the microwave irradiation on the 1,3‐Dioxa‐[3,3]‐sigmatropic rearrangement of aryl allylic carbamates was investigated. Under these new conditions, the reaction acceleration was clearly highlighted compar…
Circularly Polarized Fluorescent Helicene‐Boranils: Synthesis, Photophysical and Chiroptical Properties Open
Mono‐ and di‐boranil‐substituted helicenes were prepared by BF 2 ‐borylation of the corresponding anils, readily synthesized by condensation of 2‐amino‐ and 2,15‐diamino‐helicenes with 4‐(diethylamino)salicylaldehyde. After enantiomeric re…

An Enantiopure Cyclometallated Iridium Complex Displaying Long‐Lived Phosphorescence both in Solution and in the Solid State Open
A new enantiopure cyclometallated iridium complex bearing a [4]helicenic ‐coordinating and two ‐coordinating dfppy (2‐(2,4‐difluorophenyl)‐pyridyl) ligands was prepared. This complex displayed long‐lived phosphorescence both in solution an…
Ene reactions of 2-borylated α-methylstyrenes: a practical route to 4-methylenechromanes and derivatives Open
4-Methylenechromanes were prepared via a three-step process from 2-borylated α-methylstyrenes using a glyoxylate-ene reaction catalyzed by scandium(iii) triflate and Mitsunobu cyclization as key steps.
Stereodivergent approach in the protected glycal synthesis of L-vancosamine, L-saccharosamine, L-daunosamine and L-ristosamine involving a ring-closing metathesis step Open
In this paper, a new access to several chiral 3-aminoglycals as potential precursors for glycosylated natural products is reported from a common starting material, (−)-methyl-L-lactate. The stereodivergent strategy is based on the implemen…
