Enantioselective Total Synthesis of (−)-Dehydrobatzelladine C
摘要:
[GRAPHICS](-)-dehydrobatzelladine CThe oxidation of two tethered Biginelli adducts was examined as a potential key step in total syntheses of highly oxidized batzelladine and crambescidin alkaloids. Although angular hydroxyl substitution could not be introduced, dehydrogenation was readily accomplished. This latter conversion is a key step in the first total synthesis of dehydrobatzelladine C.
