Synthesis and antimalarial activity of 94 novel bipyrrole tambjamines (TAs) and a library of B-ring functionalized tripyrrole prodiginines (PGs) against a panel of Plasmodium falciparum strains are described. The activity and structure–activity relationships demonstrate that the ring-C of PGs can be replaced by an alkylamine, providing for TAs with retained/enhanced potency. Furthermore, ring-B of

[reaction: see text] Barton deoxygenation of 7-azabenzonorbornanols leads to a synthetically useful neophyl-like rearrangement to give 2-azabenzonorbornane derivatives in 64-90% yields.
Development of two processes for the synthesis of bridged azabicyclic systems: intermolecular radical addition–homoallylic rearrangements leading to 2-azanorborn-5-enes and neophyl-type radical rearrangements to 2-azabenzonorbornanes

Radical thiol additions to 7-azanorbornadienes give 7-thio-substituted 2-azanorbornenes and Barton deoxygenations of 7-azabenzonorbornanols give 2-azabenzonorbornanes. The processes both involve novel nitrogen-directed radicalrearrangements. The kinetics and mechanisms of the reactions are also discussed.
