Selective Synthesis of the Two Diastereomers of 5-Oxo-1H-pyrrolizine-3-carboxylic Acid
Turner, William W.
, p. 327 - 328 (2007/10/02)
The rhodium catalysed reduction of a 2,5-disubstituted pyrrole 5 occurred selectively with the cis addition of hydrogen.The resulting cis-pyrrolidine was either cyclized without epimerization in refluxing toluene to the pyrrolizine 7 or with epimerization in refluxing acetic acid to the pyrrolizine 9.
