Abstract
After stereoselective addition of N-iodosuccinimide to glycals subsequent dehalogenation results in formation of N-glycopyranosyl succinimides. By UV irradiation both azepindiones and preferentially [5.3.1.02,6] tricyclic oxalactams could be obtained. Their transformation into a number of novel sugar conjugates resembling some prominent alkaloid N-pyrrol components by thiation and reduction is reported.
