Quinindines

3-Acyl-4-methyl-1,2-dihydro-4H--quinindines (VI and III) were obtained by acylation of 1,2-dihydro-4H--quinindine (I), obtained from -quinindane methiodide (IV) by the action of alkali with acid chlorides or anhydrides. The IR and UV spectra of these ketones were studied. Quaternary salt V is formed by treatment of I with excess aliphatic acid anhydride.See 1] for communication III.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 87–90, January, 1971.
