Axially chiral BODIPYs.

چکیده
The synthesis and resolution of a class of chiral organic fluorophores, axially chiral 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes (Ax*-BODIPY), is described. Ax*-BODIPYs were prepared through a modular synthesis combined with a late stage Heck functionalisation. Resolution was achieved by preparative chiral HPLC. Absolute stereochemical assignment was performed by comparison of experimental ECD spectra with TD-DFT calculations.

Circularly Polarized Luminescence by Visible-Light Absorption in a Chiral O-BODIPY Dye: Unprecedented Design of CPL Organic Molecules from Achiral Chromophores
Circularly polarized luminescence (CPL) in simple (small, nonaggregated, nonpolymeric) O-BODIPYs (R)-1 and (S)-1 by irradiation with visible light is first detected as proof of the ability of a new structural design to achieve CPL from inherently achiral monochromophore systems in simple organic molecules. The measured level of CPL (|g(lum)|) in solution falls into the usual range of that obtai...
متن کاملBifunctional organocatalysts for the asymmetric synthesis of axially chiral benzamides
Bifunctional organocatalysts bearing amino and urea functional groups in a chiral molecular skeleton were applied to the enantioselective synthesis of axially chiral benzamides via aromatic electrophilic bromination. The results demonstrate the versatility of bifunctional organocatalysts for the enantioselective construction of axially chiral compounds. Moderate to good enantioselectivities wer...

متن کاملAsymmetric synthesis of axially chiral anilides by Pd-catalyzed allylic substitutions with P/olefin ligands.
As an attractive class of non-biaryl atropisomeric compounds, C-N axially chiral anilides have received considerable attention, and several methods have been successfully developed for their synthesis. Pd-catalyzed asymmetric allylic amination was proved to be an effective approach for the chiral anilide synthesis, although only moderate enantioselectivity and relatively narrow substrate scope ...
متن کاملOrganocatalytic atroposelective synthesis of axially chiral styrenes
Axially chiral compounds are widespread in biologically active compounds and are useful chiral ligands or organocatalysts in asymmetric catalysis. It is well-known that styrenes are one of the most abundant and principal feedstocks and thus represent excellent prospective building blocks for chemical synthesis. Driven by the development of atroposelective synthesis of axially chiral styrene der...
