Photoinduced Metalation of Nonactivated C−Cl Bonds with Samarium Diiodide: Synthesis of Alkenes with High (Z)-Selectivity through β-Elimination Reactions
摘要:
[GRAPHICS]The photoinduced metalation of nonactivated C-Cl bonds of O-acetyl chlorohydrins is promoted by samarium diiodide. As a result of this, beta-elimination of O-acetyl chlorohydrins is achieved, affording the corresponding (Z)-alkenes with total or high stereoselectivity.
