Effects of π-extension on pyrrole hemithioindigo photoswitches

The most red-shifted hemithioindigo photoswitches have been identified through systematic introduction of aryl units to a parent pyrrole hemithioindigo photoswitch. Increasing the size of the 5′-aryl substituent is ineffective at producing further redshif

Copper-Catalyzed Cascade Aminoalkynylation-Oxidation of Propargylic Alcohols: Stereospecific Synthesis of (Z)-2-Amino Conjugated Enynals/Enynones

Copper-catalyzed cascade aminoalkynylation-oxidation of propargylic alcohols has been realized, sterospecifically providing an array of (Z)-2-amino conjugated enynals/enynones in good yields under mild conditions. This transformation involves a rare 1,3-a

Modular De novo Synthesis of Unsymmetrical BODIPY Dyes Possessing Four Different Aryl Substituents

A modular synthesis of unsymmetrical BODIPY dyes based on a [6π] electrocyclization to construct both pyrrole rings is presented. The products carry four aryl moieties in positions 1, 3, 5, and 7, which can be freely selected, as well as optional substitution in positions 2 and 8. The method employs acetophenones, benzaldehydes as well as glycine nitrile or glycine ethyl ester as the key building blocks.

Synthesis, spectral-luminescent properties of B(III) and Zn(II) complexes with alkyl- and aryl-substituted dipyrrins and azadipyrrins

Effect of complexing atom, molecular structure of dipyrrolylmethene and its aza analog on spectral-luminescent properties of heteroleptic boron(III) and homoleptic zinc(II) complexes with 3,3′,5,5′-tetramethyl-2,2′-dipyrrolylmethene, 3,3′,5,5′-tetraphenyl

A new synthesis of symmetric boraindacene (BODIPY) dyes

BODIPY dyes were synthesized from pyrrole-2-carbaldehyde derivatives in high yields; this constitutes a new approach to this dye framework. The Royal Society of Chemistry.

Long wavelength heteroaryl-substituted dipyrrometheneboron difluoride dyes

This invention describes novel 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes containing heteroaryl substituents conjugated to the fluorophore and methods for their synthesis. The heteroaryl substituted compounds (heteroaryl dyes) generally have the structure: STR1 wherein any or all of the substituents R1 -R7, but at least one of such substituents, is a heteroaryl group, including 5- or 6-member rings, singly or fused, containing one or more heteroatoms. The new dyes that have spectral properties that are significantly shifted from those of the parent alkyl-substituted dyes, usually accompanied by an increase in photostability and in some cases by an increase in the extinction coefficient relative to the alkyl-substituted dyes. The general method of synthesis includes formation of pyrromethene salt intermediates followed by cyclization with boron trifluoride in the presence of a base to give heteroaryl-substituted dipyrrometheneboron difluoride dyes.
