A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, COA of Formula: C8H14ClNO3, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4644-61-5, Name is Ethyl 4-Oxo-3-piperidinecarboxylate Hydrochloride, molecular formula is C8H14ClNO3. In a Patent, authors is ,once mentioned of 4644-61-5

Substituted benzopyrano[3,4-c]pyridines having the following structural formula are disclosed: SPC1 In the above formula, R1 and R2 are hydrogen, a hydroxyl group or a lower alkoxyl group of from 1 to 6 carbon atoms; and X is an oxygen atom, a sulfur atom, a methylene group or a nitrogen atom substituted by hydrogen, a lower alkyl group of from 1 to 6 carbon atoms or a lower alkanoyl group of from 1 to 6 carbon atoms. The compounds of this invention are prepared by reacting an R1, R2 -substituted phenol with a 3-carbethoxy-4-piperidone in the presence of an acid catalyst to give an intermediate R1, R2 -substituted benzopyrano[3,4-c]pyridine. N-aminoalkylbenzopyrano[3,4-c]pyridines are obtained by treating the benzopyrano[3,4-c]pyridine with an appropriately substituted alkyl halide. The compounds of this invention are useful as bronchodilators for the treatment of bronchial asthma.
