(figure presented) Introduction of a homochiral p-tolylsulfinyl group at an appropriate position in the alkene accelerates the thermal [5C + 2C] intramolecular cycloaddition to β-silyloxy-γ-pyrones and, most importantly, leads to excellent levels of diast
A practical route to enantiopure, highly functionalized seven-membered carbocycles and tetrahydrofurans: Concise synthesis of (+)-nemorensic acid

Highly diastereoselective thermal [5C+2C] intramolecular pyrone-alkene cycloadditions can be achieved by introducing a homochiral p-tolylsulfinyl group at a suitable position of the alkene. The resulting adducts can be readily desulfinylated to give optic
