Total synthesis of the dolabellane marine diterpenoids, claenone, palominol and dolabellatrienone

The synthesis of marine dolabellane diterpenoids claenone, palominol and dolabellatrienone was conducted from D-mannitol. In each case, formation of the bicyclo[2.2.1]heptane derivative by sequential Michael reaction, preparation of the tetrasubstituted c

Total synthesis of dolabellane diterpenoid claenone

Marine dolabellane diterpenoid claenone (1) was synthesized from D- mannitol. This synthesis involves the formation of bicyclo[2.2.1] heptane derivative 4a by sequential Michael reaction, the formation of cyclopentane derivative 9 by retro-aldol reaction
