On the synthesis of isoannulated pyrroles and δ-pyridones
摘要:
The synthesis of furo- and thieno[2,3-c]pyridones 13a,b as well as the corresponding pyrroles 14a,b by using the 1,7-dipolar cyclization route of conjugated nitrones 9a,b is reported. In the presence of O2 and light the pyridones are converted into the pyridinediones 17a,b.
