In the reaction of 4a-methyl-2,3,4,4a-tetrahydro-1H-carbazole and its 6-methyl- and 6-bromosubstituted derivatives with 2-chloroacetamide respectively by 9-carbamoylmethyl-4a-methyl-2,3,4,4a-tetrahydro-1H-carbazolium chlorides are formed, which can be cyc

4aH-4a-Methyl-2,3,4,9-tetrahydrocarbazoles can be converted into 1,2,3,4,5,6-hexahydro-2,6-methano-6-methyl-1-benzazocin-11-ones by successive reaction with bromine and aqueous ammonium carbonate.
EFFECT OF THE INCLUSION OF A CYCLIC FRAGMENT IN THE CHROMOPHORE ON THE PROPERTIES OF A SPIROPYRAN-MEROCYANINE SYSTEM

The corresponding merocyanines, which do not display a tendency to form spiropyran structures, are formed in the condensation of 1,3,3-trimethyl-2-methyleneindoline with 5-methyl-2-furoylacetaldehyde, 2-formylcyclohexanone, or 2-formyl-1-tetralone.Spiran compounds in which the spiropyran-merocyanine equilibrium is shifted markedly to favor the closed form are formed when 4a,9-dimethyl-2,3,4,4a-tetrahydrocarbazone - the cyclic analog of the Fischer base - is used in the reaction with salicylaldehydes and benzoylacetaldehydes.
