摘要: The bromotropolones (1), (2), and (3) cross-couple with organostannanes in the presence of palladium(0) to produce alkyl, alkenyl, or aryl substituted tropolones; methodology has been applied synthesis monoterpenes β-dolabrin (4), β-thujaplicin (5), 7-methoxy-4-isopropyltropolone (7), β-thujaplicinol (8).
