protecting group, the free amino group is used to accomplish a second heterocyclization process onto the newly formed carbonyl group. By appropriate manipulation of these protecting groups and selection of reaction conditions, a series of pyrrolopyrazinones can be obtained in different stages of hydrogenation. hypervalent iodine - alkynylamides - reductive aminations - pyrazinones - bicyclic compounds
