An efficient enantioselective synthesis of (R)- and (S)-cizolirtine 1 is described. The key step of the procedure is the CBS-oxazaborolidine asymmetric reduction of phenyl pyrazolyl ketone 2. Related enantioselective reductions of several azolyl phenyl ketones are also reported.
The present application provides a method of treating a subject suffering from a form of urinary incontinence which comprises administering to the subject an amount of a compound having the structure:
effective to treat the subject, wherein the compound is administered in a suitable form.
The present invention relates to new 1-methylpyrazole modulators of substance P release, calcitonin gene-related peptide activity, adrenergic receptor activity, and/or 5-HT receptor activity, pharmaceutical compositions thereof, and methods of use thereof.
The process comprises (a) the enantioselective reduction of a pro-chiral ketone (III) by the use of a reducer and a chiral catalyst which have been derived from boron in a solvent or a mixture of anhydrous solvents in order to form an enantiomer of an alcohol (II), and (b) the alkylation of (II), in conditions of phase transfer, optionally after isolation and purification of the same, with 2-chloro-N, N-dimethylethylamine in order to form an enantiomer of (I). Cis-olirtine has analgesic properties.
