| Abstract: | 3,3-Dimethyl-2-oxa-1,2,3,4-tetrahydroacridine and its N-oxide and 3,3,6,6-tetramethyl-2,7-dioxa-sym-octahydroacridine N-oxide were synthesized. On heating with acetic anhydride, the N-oxides form, respectively, acetates of 3,3-dimethyl-2-oxa-1,2,3,4-tetrahydro-4-acridinol and 3,3,6,6-tetramethyl-2,7-dioxa-sym-octahydro-4-acridinol. Hydrolysis of the acetates gives the alcohols themselves. Oxidation of 3,3,6,6-tetramethyl-2,7-dioxa-sym-octahydro-4-acridinol acetate gives the corresponding N-oxide. Oxidation of 3,3,6,6-tetramethyl-2,7-dioxa-sym-octahydro-4-acridinol with manganese dioxide gives 3,3,6,6-tetramethyl-2,7-dioxa-sym-octahydro-4-acridinone.See [9] for communication VII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1218–1221, September, 1971. |
