| titleOfInvention | Process for preparing an alkyl sulfonate derivative |
| abstract | A process for preparing an alkyl sulfonate derivative comprises causing a nitrogen-containing heterocyclic compound represented by the following formula (1): ##STR1## wherein X represents --O--, --S--, --NR 1 --, --Se--, --Te-- or --CR 2 R 3 --, in which each of R 1 , R 2 and R 3 independently represents a hydrogen atom or a lower alkyl group, Y represents a hydrogen atom, a mercapto group, an arylthio group, an aralkyl group, a sulfo group, a halogen atom, an alkyl group, an alkylthio group, an alkylsulfonyloxy group or an arylsulfonyloxy group and each of R 4 , R 5 , R 6 , R 7 and R 8 represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group which may be substituted with a sulfo group, an aryloxy group, an alkylthio group, a haloalkyl group, a halogen atom, a cyano group, a carboxy group or a sulfo group, otherwise R 4 and R 5 , R 6 and R 6 , R 6 and R 7 and R 7 and R 8 are, in at least one of these combinations, bonded each other to form an aromatic ring or a cycloalkene ring; to react in the presence of Lewis acid with an aliphatic sultone to give an alkyl sulfonate derivative corresponding to the above formula (1). |
