Synthese, Struktur und Reaktionen des Epoxyfencholenaldehyds
摘要:
Fencholene aldehyde (2), a by-product of the synthesis of alpha-campholene aldehyde (1), can be obtained as main product by fenchane rearrangement of pinocarveol. Epoxidation of the protected fencholene aldehyde (3) gives the trans-epoxy-aldehyde (4) which rearranges with Lewis acids to ketone (5) and allylic alcohol (6).
