Sulfonamide derivatives of polycyclic dyes for analytical applications

摘要

1,2-Di- or 1,2,3,4-tetrahydroquinolin-4-yl-methanesulfonic acid derivatives (I) and analogous coumarin, xanthene, rhodol, carbopyronine, azine or amidopyrylium dyes (II) - (VII) are new. Di- or tetrahydroquinolinyl-methanesulfonic acid derivatives of formula (I) and polycyclic dyes of formulae (II) - (VII) are new.

INDEPENDENT CLAIM are included for: (1) the preparation of polycyclic dyes (A) by sulfonating compounds having a terminal 4-methyl-dihydroquinoline group and optionally hydrogenating to the corresponding tetrahydroquinoline (provided that (A) do not include (III; Y = O; X = OH) or (IV; X = OH)); (2) the dyes (A) obtained by the process; and (3) the preparation of (I) - (VII).
