摘要

Summary: 3-Furoic acid is converted to enaminone diester 8, which undergoes Dieckmann cyclization to yield the highly functionalized benzofuran 9. Methylation, Baeyer-Villager oxidation (CHO-OH) and conversion of the resulting hydroxy ester 10 to khellinone constitutes a formal synthesis of khellin.
