- Abstract
- Asymmetric total syntheses of ancistrocladinium A and its atropdiastereomer, in an atropisomerically pure form, are described. Chiral phosphoric acid-catalyzed asymmetric reductive amination of 1-aryl propanone and naphthylamine followed by acetylation provided two atropisomerically pure tertiary amides. Subsequent stereospecific Bischler-Napieralski reaction of each of these tertiary amides with triflic anhydride provided ancistrocladinium A or its atropdiastereomer, as a single atropisomer, respectively.
