Independent claims are also included for: (1) an intermediate of formula (III) useful in the synthesis of extended rhodamine compounds; (2) a labelled nucleoside and nucleotides of formula NUC-L-D (IV); (3) a method of fragment analysis comprising forming polynucleotide fragments labelled with (I) or (II), resolving the fragments and detected the resolved fragments. [Image] R 1 2 : H or COR 8; NUC : nucleoside or nucleotide or an analogue (provided that the linkage is attached to the 8-position of a purine, 7-position of a deazapurine or 5-position of a pyrimidine); L : linkage; D : (I) or (II). |
