Enantiomerically pure fluorinated substrates of type 1-5 undergo stereoselective radical cyclisation affording variously substituted tetrahydrofurans, cyclopentanes, and cyclohexanes. The control exerted on the formation of the new stereocentres by those already present is discussed.

Abstract
Enantiomerically pure fluorinated substrates of type 1-5 undergo stereoselective radical cyclisation affording variously substituted tetrahydrofurans, cyclopentanes, and cyclohexanes. The control exerted on the formation of the new stereocentres by those already present is discussed. Elaborations to chlorine-and sulfur-free derivatives possessing up to five stereocentres are presented.File in questo prodotto:
