Abstract

Abstract The bromotropolones (4),(5) and (10) undergo palladium-mediated cross coupling with a wide range of organostannanes to produce alkenyl-, alkyl-and aryl-substituted tropolones. The methodology has been applied to the synthesis of the monoterpenes β- dolabrin (11), β-thujaplicin (12), 4-isopropyl-7-methoxytropolone (13) and β-thujaplicinol (14). Cross coupling of bromotropolones (4),(5) and (10) with various ...
