Abstract
- The formation of tetrahydrofurans and tetrahydropyrans by acid catalyzed cyclization of hydroxy selenides can be explained by kinetic and thermodynamic control. The tetrahydropyrans from the hybrid 7-endo6-exocyclization are the thermodynamic products of the acid catalyzed cyclization of hydroxy selenides 1, whereas the tetrahydrofurans from the 5- exocyclization are the kinetic products.
