Abstract

Twenty-seven partially reduced O-, S-, and N-containing heterocvcles have been oxidized by the use of nickel peroxide. Of particular interest were the conversions of several oxazolines to the corresponding oxazoles, a conversion apparently without precedent in the chemical literature, and the efficient oxidation of thiazolines to thiazoles. Since Ni02 can effect thiazoline dehydrogenations in the presence of other functionalities, as may be judged by the successful oxidation of phleomycin A2 to bleomycin A2, the oxidant should be of utility for the preparation of natural products containing thiazoles.
