Compounds for treating abuse of nicotinic receptor agonists, addiction to psychostimulant drugs, addiction to opiates, addiction to alcohol, addiction to tobacco products, addiction to nicotine, schizophrenia and related diseases, depression and related conditions, Alzheimer's disease, Parkinson's disease, irritable bowel syndrome, and colitis. The compounds competitively inhibit central nervous system acting nicotinic receptor agonists and act at the putative &agr;3&bgr;2* and &agr;4&bgr;2 neuronal nicotinic receptors in the central nervous system.

Cyclic 2-alkyl-1,3-alkanediones are ubiquitous structural motifs in many natural products of biological importance. Reported herein is an AlCl3·MeNO2-mediated Dieckmann cyclization reaction of general synthetic utility that enables direct access to complex 2-alkyl-1,3-dione building blocks from readily available dicarboxylic acid and acid chloride substrates. This new strategy enables direct synthetic
