چکیده
Chemoselective cross-coupling reactions were demonstrated for C-S bonds in the BODIPY dyes 1 and 4, and similar reactions were applied to make the two-dye cassette system 11.

Tunable carbon-carbon and carbon-sulfur cross-coupling of boronic acids with 3,4-dihydropyrimidine-2-thiones.
Direct microwave-assisted Pd(0)-catalyzed/Cu(I)-mediated carbon-carbon cross-coupling of 3,4-dihydropyrimidine-2-thiones and boronic acids under Liebeskind-Srogl conditions leads to 2-aryl-1,4-dihydropyrimidines in moderate to high yield. In contrast, Cu(II)-mediated reaction of the same substrates leads to carbon-sulfur cross-coupling. [reaction: see text]
متن کاملSynthesis and in Vitro Studies of a Series of Carborane-Containing Boron Dipyrromethenes (BODIPYs).
A series of seven BODIPYs functionalized with ortho-carborane groups at the 8(meso) or 3/5(α) position were synthesized and characterized by NMR, HRMS, HPLC, and in the cases of 2b and 5b, by X-ray analysis. The BODIPYs exhibited low dark toxicity and phototoxicity toward human glioma T98G cells, and their cellular uptake varied significantly, with 5b accumulating the most and 7 the least. All ...
متن کاملTetracyanobutadiene functionalized ferrocenyl BODIPY dyes.
Tetracyanobutadiene (TCBD) derivatives of ferrocenyl BODIPYs 2a-2c were designed and synthesized by [2 + 2] cycloaddition-retroelectrocyclization reaction of tetracyanoethylene (TCNE) with meso alkynylated ferrocenyl BODIPYs. The TCBD substituted ferrocenyl BODIPYs were designed in such a way that the distance between the ferrocenyl unit and the TCBD remains constant, whereas the distance betwe...
متن کاملA nitroolefin functionalized BODIPY chemodosimeter for biothiols driven by an unexpected conjugated addition mechanism.
A weakly fluorescent nitroolefin functionalized BODIPY 1 was prepared and rapidly reacted with thiols through an unexpected conjugated addition to the azafulvene ring of BODIPY to generate highly fluorescent BODIPYs 4 and 5. This reaction was applied for the highly selective and sensitive detection of Cys in living cells.
متن کاملSynthesis of diverse dihydropyrimidine-related scaffolds by fluorous benzaldehyde-based Biginelli reaction and post-condensation modifications
Dihydropyrimidinones and dihydropyrimidinethiones generated from the Biginelli reactions of perfluorooctanesulfonyl-attached benzaldehydes are used as common intermediates for post-condensation modifications such as cycloaddition, Liebeskind-Srogl reaction and Suzuki coupling to form biaryl-substituted dihydropyrimidinone, dihydropyrimidine, and thiazolopyrimidine compounds. The high efficiency...
