Synthesis of coleon B tetramethyl ether

Using a simple model available from podocarpic acid, a method to synthesize the Ring A and B chromophore of coleon B (6b) was elaborated.When applied to the correctly substituted starting ketone 8, this reaction sequence afforded the first synthesis of coleon B, as the tetra-O-methyl ether 15a.
