Concise total synthesis of (±)-palominol and (±)-dolabellatrienone via a dianion-accelerated oxy-cope rearrangement
摘要:
A short synthesis of (+/-)-palominol (1) and (+/-)-dolabellatrienone (2) starting from farnesol is reported. Noteworthy steps include an intramolecular pinacol coupling to form a 15-membered carbocyclic diol and subsequent dianion-accelerated oxy-Cope rearrangement to form the 11,5-trans-fused ring system of the dolabellanes.
