Abstract: Herein, we proposed a simple approach for synthesizing 6‐H‐phenanthridine through, which was a tandem reaction and promoted by base. 2'‐Fluoro‐[1,1'‐biphenyl]‐2‐carbaldehydes and LiN(SiMe3)2 were simply added and combined to obtain different structures of 6‐H‐phenanthridines (25 examples,… read more here.

Abstract: Abstract In this study, the first asymmetric enantioselective total syntheses of (+)-asiaticumine A (2) and its enantiomer were accomplished through a seven-step sequence using the bond formation between the C4a and N5 positions of the… read more here.
