structures of acetylcholinebinding proteins (AChBPs) have revealed two different possible extensions to the classical ligand binding pocket known to accommodate variousnicotinic agonists. One of the pockets is limited in size while the other is of considerable dimensions and protrudes along the interfacial cleft between subunits. To probe these putative extensions in functional nicotinicacetylcholine receptors

hydroalkynylation of allylic alcohols protected by an oxime group. Catalytic alkynylation occurs exclusively at the distal position of the alkene. This method generates γ-alkynyl alcohol oximes directly from internal alkenes and terminalalkynes. The oxime group can be readily removed to afford a free alcohol, thus providing an indirect route for the catalytic hydroalkynylation of allylic alcohols.

active and highly (E)-selective catalyst for the olefination of a variety of aldehydes in the presence of PPh3 and diazoacetate in the ionic liquid (bmim)(PF6). Dependent on the reactivity of the applied aldehyde, the reaction can be carried out at a reaction temperature of 50–80 °C. After 0.5–24 h quantitative olefin yields are reached with a broad variety of different aldehydes. Due to the application
