| titleOfInvention | Chemoselective method of monoaminomethylation of sulfophthalein and sulfofluorescein derivatives |
| abstract | Aminomethylated sulfophthalenes and sulfofluoresceins are prepared by treating N-alkoxymethylamine, N-aryloxymethylamine, 1-N-benztriazolylmethylamine, N-imidazolylmethylamine, N-1,2,3-triazolylamine, N-1,2,3-triazolylamine, imidyloxymethylamine. acyloxymethylamine, iminomethylamine, aminomethylamine, and methylene ammonium salts to the starting sulfophthaleins of formula I wherein at least one substituent of the group R @ 2, R @ 2, R @ 3, R @ 6, R @ 6, R @ 6. or R.sup.7.n. hydrogen, to the starting sulfofluoresceins of formula (II) wherein at least one substituent of the group R @ 2, R @ 2, R @ 3, R @ 4, R @ 4, R @ 4, R @ 4, R @ 4, R @ 4, R @ 4, R @ 4. and R.sup.5.n. hydrogen, in the environment of protic or aprotic polar solvents at temperatures ranging from 25 to 300 degC. The aminomethylation by this method is highly chemoselective and regioselective. |
