Abstract:

Starting from ethyl(E)-5,9-dimethyldeca-4,8-dienoate, we developed a method for the synthesis of 6β-hydroxy-5,5,8aβ-trimethyloctahydronaphthalen-1-one(1), which was successfully applied to the establishment of the skeleton of phenylspirodrimane meroterpenoid natural products. Key steps such as regioselective epoxidation and Cp2TiCl-promoted radical cascade cyclization have been optimized. The structures of the compounds synthesized have been characterized with nuclear magnetic resonance spectroscopy(NMR) and high resolution mass spectrometry(HRMS).

Key words: 6β-Hydroxy-5,5,8aβ-trimethyloctahydronaphthalen-1(2H)-one, Phenylspirodrimanes meroterpenoids, Epoxidation, Free radical tandem cyclization
