Abstract
3-(Trimethylstannyl)-5-bromo-2-pyrone underwent facile Stille coupling reactions with aryl halides to produce various 3-substituted 5-bromo-2-pyrones. The resulting 3-aryl-2-pyrone derivatives underwent both normal and inverse electron demand D-A cycloadditions depending on the type of the dienophiles being reacted.
