Anisodine

Anisodine, also known as daturamine and α-hydroxyscopolamine, is an antispasmodic and anticholinergic drug used in the treatment of acute circulatory shock in China. It is a tropane alkaloid and is found naturally in plants of the family Solanaceae - notably Anisodus tanguticus (syn. Scopolia tangutica. Anisodine acts as a muscarinic acetylcholine receptor antagonist and α1-adrenergic receptor antagonist.

Synthesis
(-)-Anisodine can be efficiently prepared using 6-beta-acetyltropine as the starting material via a key step of the Sharpless asymmetric dihydroxylation (AD).
