A flexible approach to hexahydronaphthalene-1-carboxylates
摘要:
A flexible approach to hexahydronaphthalene-1-carboxylates based on the Favorskii rearrangement of 1,1-dichloro bicyclo[5.4.0]undec-5-en-2-ones has been devised. 1,1-Dichloro bicyclo[5.4.0]undec-5-en-2-ones can be prepared from readily available cyclohexanones by a short sequence.

Vinylic halides or triflates react with 3-butenoic or 4-pentenoic acids in the presence of 5% Pd(OAc)2 or Pd(dba)2, -Bu4NCl, -PrNEt2 and either acetonitrile or ,-dimethylformamide at 80–100°C to afford the corresponding γ-alkenyl-γ-butyro- or δ-alkenyl-δ-valerolactones respectively by an intramolecular π-allylpalladium displacement process.
