摘要: Diazomethane ring expansion of 12-acetoxy-C2-bismethanotwistan-8-one (11) followed by the Wolff–Kishner reduction and Jones oxidation gave C2-methanoditwistan-4-one (14) whose incubation with Rhodotorula rubra afforded (−)-enantiomer 16, which was converted into (−)-(1S,3S,6S,7S,10S,12S)-D3,-tritwistane (7).
