Nitrones and Oxaziridines. XXXIX Conversion of 1-Pyrroline 1-Oxides into 2H-Pyrroles through the Hetero-Cope Rearrangement
Black, David, St.C.,Strauch, Richard J.
, p. 71 - 78 (2007/10/02)
The 1-pyrroline 1-oxides (1) undergo a hetero-Cope rearrangement to give variously the 2H-pyrroles (2) and/or the 3-benzoyloxy-1-pyrrolines (3).The esters (3) can be hydrolysed to the corresponding alcohols (4).
