Enantioselective Total Synthesis and X-ray Structures of the Tetrahydroprotoberberine Alkaloids (−)-(S)-Tetrahydropalmatrubine and (−)-(S)-Corytenchine

AL Zein, LN Dawe, PE Georghiou - Journal of natural products, 2010 - ACS Publications
Enantioselective total syntheses and X-ray structures of both (S)-tetrahydropalmatrubine (2)
and (S)-corytenchine (3) are reported for the first time. They were both derived from (S)-N …
