Oxidative rearrangement of cyclobutanone derived N,O-ketals leading to pyrrolidone derivatives



Oxidative rearrangement of cyclobutanone derived N,O-ketals leading to pyrrolidone derivatives



Chemical and Pharmaceutical Bulletin 63(4): 245-247



A halogen-induced oxidative rearrangement of N,O-ketals prepared from cyclobutanones, leading to pyrrolidone derivatives, is developed. The reaction proceeds via an iminium ether intermediate and, depending on the reaction medium, two types of pyrrolidone derivative, containing a halogen atom or hydroxyl group, can be obtained.
