Mason, Stephen J. published the artcileSolid-phase catch, activate, and release synthesis of cyanine dyes, Recommanded Product: 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Organic Letters (2002), 4(24), 4261-4264, database is CAplus and MEDLINE.
Trimethine cyanine dyes were synthesized by capture and activation of a hemicyanine intermediate on a sulfonyl chloride resin followed by reaction and concomitant cleavage by a heterocyclic carbon nucleophile. A small array of dyes was synthesized and characterized to demonstrate the versatility of this chem. for a number of hemicyanines and heterocyclic nucleophiles.
