2,2,10-Trimethyl-2,3-dihydropyrano[2,3-a]carbazol-4(11H)-one
The title compound, C18H17NO2, was prepared from 1-hydroxy-8-methylcarbazole and 3,3-dimethylacrylic acid with trifluoroacetic acid as the cyclization catalyst. Due to the –CMe2– group, the molecule is not quite planar. The packing is dominated by the strong N—H...O hyd...
