The Isomerization of 1aH-Oxazirino [2, 3-α] quinoline 1a-carbonitrile and Its Substituted Derivatives to the Corresponding 3-Hydoxyquinoline Derivatives

Abstract

The oxaziranes (Ia∼d) prepared by the irradiation of the corresponding 2-cyanoquinoline 1-oxides in an aprotic solvent all rearranged to the corresponding 3-quinolinols under a variety of conditions described. The mechanism of this novel isomerization has been postulated.
