Synthesis of fluorescent rhodamine dyes using an extension of the Heck reaction

Both benzo[b]thiophene and indole containing rhodamine dyes were synthesized according to a new pathway requiring a Heck-type coupling and a Pictet-Spengler reaction. The electron-rich indolic dye was shown to have noteworthy absorption and emission maxim

Heck-like coupling and Pictet-Spengler reaction for the synthesis of benzothieno[3,2-c]quinolines

A series of 6-arylbenzothieno[3,2-c]quinolines were synthesised in three steps from benzo[b]thiophene. After a selective Heck-type coupling of benzo[b]thiophene with different o-nitroaryl bromides to obtain 2-(o-nitroaryl)benzo[b]thiophenes, corresponding

Benzo[b]thiophene as a template for substituted quinolines and tetrahydroquinolines

An original methodology starting from 3-aroyl-2-(2′-nitro-4′- methoxyphenyl)-benzo[b]thiophene allows the synthesis of unusual fused heterocycles. Direct hydrogenation with nickel catalysts followed by desulfurisation led to 2,3-diarylquinolines or 2,3-di

Derivatives of 1,2-dihydro-7-hydroxyquinolines containing fused rings

The present invention describes novel dyes, including coumarins, rhodamines, and rhodols that incorporate additional fused aromatic rings. The dyes of the invention absorb at a longer wavelength than structurally similar dyes that do not possess the fused aromatic rings. Many of the dyes of the invention are useful fluorescent dyes. The invention includes chemically reactive dyes, dye-conjugates, and the use of such dyes in staining samples and detecting ligands or other analytes.

Rational design and synthesis of a novel class of highly fluorescent rhodamine dyes that have strong absorption at long wavelengths

A novel class of strongly fluorescent rhodamine dyes were designed and synthesized by extending the π conjugation of chromophore with limited flexibility. These dyes were shown to have longer absorption in the range of 581 to 631 nm with quantum yields between 0.64 and 0.89.
