Abstract: Certain dihydroxyindanone compounds, and their pharmaceutically-acceptable salts, are inhibitors of tyrosine kinase enzymes, and so are useful for the control of tyrosine kinase dependent diseases (e.g., cancer, atherosclerosis).
Abstract: The present invention is directed to a method for the recovery of erythorbates from photographic solutions. In the disclosed method, the photographic solution is first acidified by passing it over an acidic cation exchange resin and the resultant solution is then passed over a weakly basic anion exchange resin.
Abstract: (C.sub.1 -C.sub.3)Alkyl-4,6,7,8,9,9a-hexahydro-2H,3H-pyrido[1,2-a]pyrazin-1-one-7-c arboxylate esters, important precursors to certain bis-aza-bicyclic anxiolytics, can be prepared from di(C.sub.1 -C.sub.3)alkyl cis-piperidine-2,5-dicarboxylate starting material by a new process via a new class of intermediates, di(C.sub.1 -C.sub.3)alkyl cis-N-(2-(phthalimido)ethyl)piperidine-2,5-dicarboxylates. In the process, the starting material is reacted with either 2-(phthalimido)ethyl triflate or 2-(phthalimido)acetaldehyde to form the new intermediate, which can then be cyclized to the aforementioned precursor.
