Synthesis of (+)-cyclozonarone and the absolute configuration of naturally occurring (-)-cyclozonarone.
Synthesis of (+)-cyclozonarone (1) has been achieved using (-)-polygodial (3) as chiral starting material. The absolute configuration of naturally occurring (-)-cyclozonarone was established as 5R,10R by comparison of spectral data and optical rotation with those of (+)-cyclozonarone.
