Org Lett. 2015 Aug 21;17(16):3944-7. doi: 10.1021/acs.orglett.5b01474. Epub 2015 Aug 07.

A base-catalyzed selective cycloisomerization of 3-aza-1,5-enynes is developed. This transformation provides a facile access to highly functionalized 2-azabicyclo[3.2.0]hept-2-enes and sulfonyl vinyl-substituted pyrroles. The chemoselectivity was controlled by the substituent pattern of the substrates.

Ruthenium-Catalyzed C-C Bond Cleavage of 2H-Azirines: A Formal [3+2+2] Cycloaddition to Fused Azepine Skeletons.
