Described are novel amino- and iminoalkyl piperazines having affinity for serotonergic receptors and pharmacological compositions thereof. These compounds and their isomers, including optical isomers, enantiomers, diastereomers, N-oxides, polymorphs, hydrates, solvates and pharmaceutically acceptable salts are useful in the treatment of patients with neuromuscular dysfunction of the lower urinary tract and CNS diseases and/or disorders associated with 5-HT

A remarkable proline-catalyzed method for the construction of biologically interesting oxygen-bridged tricyclic ketal skeletons was uncovered by starting from a variety of readily available cyclic 1,3-diketones and either 1,4- or 1,5-dicarbonyl substrates. The approach, which mimics a biosynthetic Knoevenagelcondensation/[4+2] cycloaddition sequence, establishes a viable synthetic strategy for the

Substituted γ and δ-ketoaldehydes may be conveniently synthesized in two steps from imine carbanions, which are obtained by reaction with hyperbasic media. These anions are stable at low temperature (−30°); they react with functional electrophiles to afford masked ketoaldehydes which may be cyclised into various cyclopentenones or cyclohexenones.
