O-Arylsulfonyl hydroxylamines via a decarboxylative rearrangement
摘要:
(E)-O-aryl-sulfonyl-N-[2-nitroalk(-2-enyl)]hydroxyl-aamines were readily obtained with good yields starting from (E)-nitro-allyl-alcohols, the crucial step being an inorganic base-catalyzed de-carboxylative rearrangement of proposed labile unstable carbamates. A possible mechanism for the reaction, characterized by the unusual retention of the sulfonyl-oxy group, is proposed. (C) 2009 Elsevier Ltd. All rights reserved.
