PREPARATION AND DIELS–ALDER REACTIONS OF SOME FUNCTIONALIZED ISOPRENES

Abstract
A convenient synthetic method for some functionalized isoprenes employing 1-bromo-2-phenylthioethane and ethyl acetoacetate as starting materials is reported. It has also been found that the dienes thus obtained gave functionalized limonene analogs by Diels–Alder reaction with methyl vinyl ketone.
