The asymmetric synthesis of 8,4′-oxyneolignans (−)-virolin, (−)-surinamensin and a number of analogues has been achieved. A divergent synthesis was used, with all compounds being elaborated from a single chiral aldehyde derived from ethyl lactate. In the 15 compounds that were tested, the level of substitution on the A-ring was found to directly influence the activity against Leishmania donovani whilst
