Quinindines

The Mannich reaction and hydroxymethylation of -quinindane at the 3 position were studied. The dialkylaminomethyl derivatives readily split out dialkylamine to form 3-methylene--quinindane, the structure of which was proved by the IR, UV, and PMR spectra. The dipole moments and pK values of the compounds were measured. No tetracyclic compounds are formed; the reaction ceases at the step involving formation of N-phenacylido--quinindane.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1530–1534, November, 1970.     

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.
