Enantioselective Total Synthesis of the (−)-(6R,11R,14S)-Isomer of Colletallol
摘要:
The total synthesis of the (-)-(6R,11R,14S)-isomer of colletallol was achieved in 15 steps. The key steps of the sequence were the building of the macrocycle via two consecutive Wittig reactions, the first intermolecular and the second intramolecular, instead of the classical macrolactonization methods.
