The stereocontrolled total synthesis of (-)-ephedradine A (1) has been accomplished. Construction of optically active dihydrobenzofuran-ring was performed by a novel asymmetric C-H insertion reaction. After an intramolecular ester-amide exchange reaction and a Sharpless asymmetric aminohydroxylation reaction, construction of the complex macrocyclic ring was performed by Ns-strategy and an intramolecular aza-Wittig reaction.

The stereocontrolled total synthesis of (-)-ephedradine A has been accomplished. The synthesis features an asymmetric C-H insertion reaction, an intramolecular ester-amide exchange reaction, and a Sharpless asymmetric aminohydroxylation reaction. Construction of the complex macrocyclic ring was performed by Ns-strategy and an intramolecular aza-Wittig reaction. Copyright
