Bicyclo[2.2-1]heptanes as novel triple re-uptake inhibitors for the treatment of depression

A series of substituted naphthyl containing chiral [2.2.1] bicycloheptanes were prepared utilizing asymmetric Diels-Alder chemistry. This paper describes structure-activity relationships in this series. The N-methyl 2-naphthyl analogue (16d) and its des-methyl analogue (17d) are active triple re-uptake inhibitors both in vivo and in vitro.

Synthesis of pyridine fused polycyclic amines using sequential ring-closing metathesis and radical cyclisation reactions

The syntheses of novel pyridine fused polycyclic bridgehead amines are described using sequential ring-closing metathesis (RCM) and 5-exo-trig intramolecular radical cyclisation reactions. Critical to the success of the two sequential steps were the RCM catalyst and/or the nature of the nitrogen atom.

The regioselective aminohydroxylation of allylic carbamates

The synthesis and aminohydroxylation of a series of acyclic allylic carbamates is described: the formation of a putative O=Os=NR linkage between the transition metal and substrate is proposed to account for the high levels of regioselectivity that were observed; proof of the structure of one of the aminohydroxylation products was obtained through X-ray crystallography.
