Taxane diterpenes .3. Formation of the eight-membered B-ring by semi-pinacol rearrangement
The substituted furan carboxaldehyde 15 was converted into enone 20 via a stereoselective intramolecular pyrylium ylide-alkene cyclization. Subsequent elaboration of 20 into the triflate 23, followed by solvolysis in acidic trifluoroethanol resulted in quantitative rearrangement to the taxane B/C co...
