An efficient one-pot synthesis of anthraquinones and tetracenediones was achieved by l-proline catalyzed benzannulation of commercially available 1,4-naphthoquinones or 1,4-anthracenedione with a variety of α,β-unsaturated aldehydes in good to excellent yield.

farnesyltransferase inhibitory activity in the low micromolar range. A preliminarystructure–activityrelationship (SAR) study has identified different structural requirements for anti-malarial activity in comparison to FTase activities for these classes of natural products. Our results identify tecomaquinone I as a novel scaffold from which more potent inhibitors of human and parasitic FTase could be developed.
Palladium-catalyzed remote arylative substitution was achieved for the reaction of arylboronic acids with alkenes possessing a distant acetoxy group via nondissociative chain walking and β-acetoxy elimination.

Disclosed is a ligand regulated protein-protein interaction system based on a lipocalin-fold molecule comprising:
(a) a lipocalin-fold molecule
(b) a lipocalin-fold ligand with a low molecular weight of 1500 Da or below, and
(c) a lipocalin-fold binding interaction partner,
wherein the lipocalin-fold molecule can bind to the lipocalin-fold ligand; and
wherein the lipocalin-fold molecule bound to the lipocalin-fold ligand binds to the lipocalin-fold binding interaction partner with an affinity which is at least 10-fold higher than the affinity of the lipocalin-fold molecule not bound to the lipocalin-fold ligand,
and wherein the lipocalin-fold binding interaction partner is not a naturally occurring protein which has an affinity of <10 µM to any naturally occurring lipocalin-fold molecule in the presence of any lipocalin-fold ligand.
