Conversion of F-BODIPYs to Cl-BODIPYs: Enhancing the Reactivity of F-BODIPYs

The Journal of Organic Chemistry, 2012
A new method for the synthesis of Cl-BODIPYs from F-BODIPYs is reported, merely requiring treatment of the F-BODIPY with boron trichloride. Cl-BODIPYs are exploited as synthetic intermediates generated in situ for the overall conversion of F-BODIPYs to O- and C-BODIPYs in high overall yields using a mild one-pot procedure.

Cl-BODIPYs: a BODIPY class enabling facile B-substitution

Chem. Commun., 2012
Cl-BODIPYs, synthesized in high yields from dipyrrins under air- and moisture-free conditions, are extremely facile to substitution at boron compared to their corresponding F-BODIPYs, opening up a new route to BODIPYs functionalized at boron.

Boron Asymmetry in a BODIPY Derivative

Organic Letters, 2010
A boradiazaindacene (BODIPY) fluorophore with a chirality held on the central boron has been synthesized and the racemate resolved. Dissymetrization of the BODIPY core was obtained by oxidation of the 3-methyl group to the corresponding carboxaldehyde. A hydrogen bond between the aldehyde proton and the fluorine on the boron atom was evidenced by both (

Aza-BODIPY Route to Ageladine A

Organic Letters, 2022
The marine natural product ageladine A was synthesized by exploiting novel aza-BODIPY-type boron complexes that allowed the regioselective dibromination of the pyrrole unit, as confirmed by quantum chemical calculation (ωB97XD/TApr-cc-pVDZ). The parent tricycle was accessed by Suzuki-Miyaura cross-coupling employing Buchwald's precatalyst.

Cyclic Azobenzene‐BODIPY Hybrids

Chemistry – A European Journal, 2023
AbstractCyclic azobenzene‐BODIPY hybrids were synthesized via cyclization by 1) acid‐catalysed condensation of azobenzene‐bridged dipyrroles with 3,5‐di‐tert‐butylbenzaldehyde, 2) oxidation with DDQ, and 3) metalation with BF3 ⋅ Et2O. The structures of many cyclic hybrids have been confirmed by single crystal X‐ray analysis.

Synthesis and application of methylthio-substituted BODIPYs/aza-BODIPYs

Dyes and Pigments, 2017
Abstract A series of new BODIPYs/aza-BODIPYs with a methylthio group were Herein prepared. Introduction of the electron-donating methylthio substituent into such dyes could reduce the fluorescence quantum yield, red-shift its emission spectra, provide higher extinction coefficients and larger Stokes' shift.

Synthesis of Functionalized BODIPYs, BODIPY‐Corrole, and BODIPY‐Porphyrin Arrays with 1,2,3‐Triazole Linkers Using the 4‐Azido(tetrafluorophenyl)‐BODIPY Building Block

European Journal of Organic Chemistry, 2015
AbstractThe copper(I)‐catalyzed 1,3‐dipolar cycloaddition of 4‐azido(tetrafluorophenyl)boron‐dipyrrin (azido‐BODIPY) with diverse terminal alkynes, varying from simple alkyl‐substituted derivatives to alkynes with functional groups and carbohydrates, was successfully employed to obtain meso‐functionalized BODIPY derivatives through the 1,2,3‐triazole ...

Masking and Demasking Strategies for the BF₂–BODIPYs as a Tool for BODIPY Fluorophores

The Journal of Organic Chemistry, 2014
An efficient and chemoselective route for transforming BF2-BODIPYs to Et2B-BODIPYs (masking) was developed using Et2AlCl. The Et groups can be easily replaced with F atoms using BF3·Et2O in moist CH2Cl2 to regenerate the BF2-BODIPYs (demasking). The masking-demasking strategy is very useful for synthesizing functionalized BODIPYs via nucleophilic and ...
