NEW DIHYDROFURAN AND DIHYDROPYRAN DERIVATIVES BY IODOENOLCYCLIZATION OF 2-PRENYL-1,3-DICARBONYL COMPOUNDS: STUDIES ON THE REGIOCHEMISTRY

Roberto Antonioletti, F. D'ONOFRIO, Barbara Rossi

Abstract

Both dihydrofuran and dihydropyran derivatives are obtained performing iodoenolcyclization of 2-alkenyl-1,3-dicarbonyl compounds having a highly substituted double bond. The regiochemistry is greatly dependent on the nature of carbonyl groups.
