Samsoniya, M. Trapaidze, N. Nikoleishvili, K. Japaridze, J. Maisuradze, U. Kazmaier] The synthesis of new condensed indoline bis-spiropyrans from isomeric hexamethyldihydroindolo-[4,5-e]-and -[7,6-g]indoles, and also from hexamethyldihydrobenzo[e]pyrrolo[3,2-g]indole in three stages has been generalized. By condensation of the isomeric bis-analogs of Fischer's bases obtained at the second stage with salicylic aldehydes, the following bis-spiro compounds have been synthesized: 6,6"-dinitro-, 6,6",8,8"-tetranitro-, 6,6",8,8"-tetrabromo-1',3',3',6',8',8'-hexamethyldispiro[chromene-2,2'-indolino[7,6-g]indoline-7',2"-chromenes], 6,6"-dinitro-, 6,6",8,8"-tetranitro-, 6,6",8,8"-tetrabromo-1',1',3',8',10',10'-hexamethyldispiro[chromene-2,2'-indolino[4,5-e]indoline-9',2"-chromenes], 6,6"-di-nitro-, 6,6"-dibromo-, and 6,6",8,8"-tetrabromo-1',1',8,8'-tetramethyl-1',4',5',8'-tetrahydrodispiro-[chromene-2,2'-dipyrrolo[1,2,3-d,e:3,2,1-i,j]benzo[g]quinoxaline-7',2"-chromenes].
