Abstract

The total synthesis of (±)-royleanone (I) has been achieved. 5, 7, 8-Trimethoxy-1-tetralone (III) was converted into (±)-5, 7, 8-trimethoxy-1-methyl-2-tetralone (VII) via a dihydronaphthalene derivative (IV). The annelation of VII with methyl vinyl ketone gave a (±)- hexahydro-2-oxophenanthrene derivative (VIII), which was then further converted into (±)- 11, 12, 14-trimethoxy-3-oxopodocarpa-5, 8, 11, 13-tetraene (IX). The hydro-genation of IX ...
