摘要:
Disclosed is a process for the oxidation of sulphonamides of formula (I) to N-sulphonyl imines of formula (II) using chromium (IV) dioxide as the oxidant. Also disclosed is a process for the preparation of imines of formula (iii) or combinatorial libraries thereof by removal of the sulphonyl group. In the formulae (I, II, III), R1 and R2 are independently selected from the group consisting of hydrogen and organic radicals not possessing a hydrogen atom in the position beta to the nitrogen atom of the sulphonamide group; and R3 is an organic radical selected from the group consisting of alkyl, substituted alkyl, aryl, and substituted aryl groups, and optionally R1 and R2 can form a ring.
