- Rearrangement of differentially protected N-arylhydroxylamines
-
The rearrangement of a series of N,O-difunctionalised N-arylhydroxylamines to generate protected 2-aminophenols has been investigated. N-Boc-N-Aryl-O- acylhydroxylamines are stable, isolable compounds which rearrange smoothly at temperatures between 110 and 140°C. The corresponding N-Boc-N-aryl-O- sulfonylhydroxylamines were not isolated and rearrange to 1,2-difunctionalised aminophenols at room temperature in excellent yield. Deprotection of either the N- or O-substituents under standard conditions allows for further synthetic manipulation of either the aniline or phenol functionality. Wiley-VCH Verlag GmbH & Co.
