Non-nucleoside phosphoramidites of xanthene dyes (FAM, JOE, and TAMRA) for oligonucleotide labeling.
    Current protocols in nucleic acid chemistry, 2013, Volume: Chapter 4

    This unit describes the preparation of 5- and 6-carboxy derivatives of the xanthene fluorescent dyes fluorescein (FAM), 4',5'-dichloro-2',7'-dimethoxy-fluorescein (JOE), and tetramethylrhodamine (TAMRA) as individual isomers, and their conversion to non-nucleoside phosphoramidite reagents suitable for oligonucleotide labeling. The use of a cyclohexylcarbonyl (Chc) protecting group for blocking of phenolic hydroxyls facilitates the chromatographic separation of isomers of carboxy-FAM and carboxy-JOE as pentafluorophenyl esters. Acylation of 3-dimethylaminophenol with 1,2,4-benzenetricarboxylic anhydride gave a mixture of 4-dimethylamino-2-hydroxy-2',4'(5')-dicarboxybenzophenones, easily separable into individual compounds upon fractional crystallization. Individual isomeric benzophenones are precursors of 5- or 6-carboxytetramethylrhodamines. The dyes were converted into 6-aminohexanol- (JOE), 4-trans-aminocyclohexanol- (FAM and JOE), and hydroxyprolinol-based (TAMRA) phosphoramidite reagents.
