โœฆ Synopsis

We describe a synthesis of 2E-pyrrole l-oxides (3) from the 3-bromopyrroline l-oxides (2). Bromination in the 3-position of 1-pyrroline l-oxides appears to be a general reaction and the 2-cyano-1-pyrroline l-oxides (1) undergo reaction with E-bromosuccinimide (NBS) to form the monobromo nitrones (2) in approximately 70% yield. These

Some C5 mono-and diester-substituted 1-pyrroline-1-oxides have been prepared via reductive cyclisation of the corresponding g-nitro carbonyl compounds. Ethyl 2-phenyl-1-pyrroline-1-oxide-5-carboxylate 5c was regioselectively alkylated at C5. Acylation of this molecule occurs exclusively on the nitro
