摘要

Lactams and pyridines are privileged scaffolds, but strategies for combining these groups into one molecule are lacking. Now, N-N pyridinium ylides have been shown to form triplet state diradicals under photoinduced energy transfer, and subsequent [3+2] cycloaddition with the tethered alkene enables the synthesis of diverse ortho-pyridyl lactams.
