Intramolecular photocyclisation reactions of 5-tert-butyldimethylsilyloxymethyl-3-(3-formylpropyl)furan-2(5H )-one: formation of bicyclic and spirobicyclic lactones

Abstract

5-tert-Butyldimethylsilyloxymethyl-3-(3-formylpropyl)furan-2(5H )-one has been synthesised and upon irradiation yields either one homochiral bicyclic lactone or a mixture of spirobicyclic lactones (in modest yield) depending upon the irradiation conditions.
