First total synthesis of (−)- and (+)-6-O-desmethylantofine†
Abstract
The first total synthesis of (−)-6-O-desmethylantofine (A) and its unnatural enantiomer (+)-6-O-desmethylantofine (B) is described. The synthetic route is efficient and practical with easily available glutamic acid dimethyl ester hydrochloride as the chiral material under mild conditions.
