A very short and efficient synthesis of (+)-conocephalenol
摘要:
The synthesis of (+)-conocephalenol, a brasilane sesquiterpenoid alcohol, was achieved in seven steps from (R)-pulegone with an overall yield of 15%. The key steps were a radical addition of a tertiary radical to the electrophilic radicophile, (R)-3-methyl-2-methylenecyclopentanone, and an aldol cyclization under acidic conditions.

Two short and efficientsyntheses of (+)-conocephalenol are described from (R)-pulegone. The key steps are radical additions of tertiary radicals to enones and an intramolecular aldol cyclization under acidic conditions.
