RESUMO
The first asymmetric total synthesis of andranginine (1) via an asymmetric Morita-Baylis-Hillman reaction and a diastereoselective intramolecular Diels-Alder reaction has revealed that natural andranginine (1) isolated from Kopsia arborea existed as a scalemic mixture and contained predominantly the (16R,21S) form rather than the (16S,21R) form.
