The first synthesis of (−)-laurequinone, cyclolaurane-type sesquiterpenoid isolated from the red alga Laurencia nidifica, has been achieved by using an intramolecular Heck reaction and an insertion of carbene as the key steps for the construction of quaternary carbon at the benzylic position and cyclopropane ring, respectively.
