Using two catalytic ring closing metatheses the key events, a short, completely diastereoselective and highly enantioselective access to the molluscicidal sesquiterpenoids ricciocarpin A and ricciocarpin B was achieved. The hitherto unknown absolute configuration of these natural products is unambiguously established.
