A stereocontrolled construction of rel-(7S,8S,7'R,8'S)-7,7'-epoxylignan skeleton
摘要:
We have developed a highly diastereoselective route to construct rel-(7S,8S,7'R,8'S)-7,7'-epoxylignan skeleton, wherein stereocontrolled Michael addition to gamma-oxyenone intermediate and subsequent alpha-alkylation to the resulting ketone are keys to the synthesis.
