Abstract

An improved synthesis of MDL 73811 – a potent AdoMetDC (S-adenosylmethionine decarboxylase) inhibitor and anti-trypanosomal compound with in vivo activity – has been completed in four steps from commercially available 2′,3′-O-isopropylideneadenosine. Utilization of Mitsunobu chemistry was crucial for the reliable and scalable introduction of the 5′-methylamine moiety, which was problematic using traditional activation/displacement chemistry as previously reported. All reactions in this synthesis were run on gram-scale resulting in a five-fold increase in yield over the original synthesis.
