【 摘 要 】

An unusual bicyclic hydroxamate resulted from C-O bond cleavage of acylnitroso hetero-Diels-Alder cycloadducts when treated with catalytic Bronsted acids under anhydrous conditions. Similarly, the formation of a nitrone was observed using one equivalent of triflic acid. (C) 2008 Elsevier Ltd. All rights reserved.
