A stereoselective approach to annulated tetrahydrofurans by iodocyclisations of 2-alkenylcloalkan-1-ols
Abstract
Highly stereoselective iodocyclisations of the 2-alkenylcycloalkan-1-ols 7, 8, 10 and 11 under strictly anhydrous conditions give good to excellent yields of the annulated β-iodotetrahydrofurans 12-16.
