Preparative Flash Vacuum Pyrolysis : Formation of 3-Substituted Furans via Stereospecific Synthesis of Endo/Exo Alkyl (Aryl)-3-Methylene-6,9-Oxa-1-Spiro[4,5] Decadiene-3,7

Abstract
Endo/exo alkyl (aryl)-3-methylene-6,9-oxa-1-spiro[4,5] decadiene-3,7 were synthesized and provide facile access to furan derivatives.
