The first enantioselective total synthesis of epiplakinic acid F (1) was achieved through a pivotal step involving a radical-mediated asymmetric peroxidation of vinylcyclopropanes with molecular oxygen to construct highly substituted 1,2-dioxolanes. Subsequent conversions of the chiral 1,2-dioxolanes led to total synthesis of epiplakinic acid F (1) and the confirmation of its absolute configuration. The enantiomer of epiplakinic acid F methyl ester (2) was also prepared. This journal is the Partner Organisations 2014.

The synthesis of a series of N-alkylated 4-(4′aminobenzyl)-2-oxazolidinones is described using a synthetically useful scheme which avoids the use of phosgene - since the derivatization is undertaken with the oxazolidin-2-one ring intact. The compounds were tested for human placental aromatase (AR) inhibition in vitro, using [1β, 2β-3H]androstenedione as substrate for the AR enzyme. The compounds were found, in general, to be more potent than the standard compound, amino-glutethimide (AG), and as such proved to be good lead compounds in the search for more specific AR inhibitors.

The design and synthesis of a series of novel 5-substituted tryptamines with pharmacological activity at 5-HT1D and other monoamine receptors is described.Structural modifications of N- and C-linked (prinicipally hydantoin) analogues at the 5-position were synthesized and their pharmacological activities were utilized to deduce significant steric and electrostatic requirements of the 5-HT1D and 5-HT2A receptor subtypes.Conformations of the active molecules were computed which, when overlaid, suggested a pharmacophore hypothesis which was consistent with the affinity and selectivity measured at 5-HT1D and 5-HT2A receptors.This pharmacophore is composed of a protonated amine site, an aromatic site, a hydrophobic pocket, and two hydrogen-bonding sites.A 'selectively site' was also identified which, if occupied, induced selectivity for 5-HT1D over 5-HT2A in this series of molecules.The development and use of the pharmacophore models in compound design is described.In addition, the physicochemical constraints of molecular size and hydrophobicity required for efficient oral absorption are discussed.Utilizing the pharmacophore model in conjuction with the physicochemical constraints of molecular size and log DpH7.4 led to the discovery of 311C90 (6), a new selective 5-HT1D agonist with good oral absorption and potential use in the treatment of migraine.
