Silver-Mediated Synthesis of Indolizines via Oxidative C-H functionalization and 5- endo-dig cyclization.

Tetrahedron Lett. 55(50) , 6922-6924, (2014)

An efficient strategy for the synthesis of indolizines from readily available starting materials via oxidative C-H functionalization and 5-endo-dig cyclization in one step has been demonstrated. This ...
