Synthesis of furanoid terpenes via an efficient palladium-catalyzed cyclization of 4,6-dienols
摘要:
The total syntheses of marmelo oxides A and B and a terpene alcohol found in peppermint oil are described. The key steps in these syntheses are the regioselective palladium-catalyzed allylic substitution of 4 and 11 to 6a and 12, respectively, and the regioselective palladium-catalyzed cyclization of 8 and 14 to 9a, 9b, and 15, respectively. The relative stereochemistry of marmelo oxides A and B was established by NOE measurements.
