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
An efficient synthesis of optically active trans-2-Aryl-2,3-dihydrobenzofuran-3-carboxylic acid esters via C-H insertion reaction

, p. 1028 - 1030 (2007/10/03)
Optically active trans-2-Aryl-2,3-dihydrobenzofuran-3-carboxylic acid esters were synthesized by intramolecular C-H insertion reaction. Upon treatment with a catalytic amount of Rh2(R-DOSP)4, aryldiazoester 8c possessing a chiral auxiliary underwent C-H insertion reaction to give 9c in high yield and in high selectivity (84% yield, 86% de).
