Total synthesis of (+)-4,5-deoxyneodolabelline
Williams, David R.,Heidebrecht Jr., Richard W.
, p. 1843 - 1850 (2003)
The first total synthesis of the marine dolabellane diterpene (+)-4,5-deoxyneodolabelline (1) has been accomplished. The highly efficient approach is characterized by the convergent assembly of dihydropyrans 2ab and cyclopentylsilanes 3ab. Allylic silane
