Stereoselective total synthesis of (±)-fragranol by TiCl4 promoted [2+2] cycloaddition of allyl-tert-butyldiphenylsilane and methyl methacrylate†
Abstract
A stereoselective total synthesis of the monoterpenoid alcohol (±)-fragranol has been accomplished utilizing a TiCl4 promoted [2 + 2] cycloaddition of allyl-tert-butyldiphenylsilane and methyl methacrylate as the key step.
