Concise Total Synthesis of (−)-Deoxocuscohygrine and (−)-Dihydrocuscohygrine
摘要:
GraphicsThe concise enantioselective total synthesis of C(2)-asymmetrical (-)-deoxocuscohygrine and (-)-dihydrocuscohygrine are described. Double-diastereoselective additions of normal Grignard reagent to bis(1.3-oxazolidine) have been deployed to construct chiral diamine fragments as a key step.
