2,2-Dimethyl-2,3-dihydro­pyrano[2,3-a]carbazol-4(11H)-one

The title compound, C(17)H(15)NO(2), was prepared from 1-hydroxy­carbazole and 3,3-dimethyl­acrylic acid with a mixture of AlCl(3) and POCl(3) as the cyclization catalyst. Owing to the presence of the –CMe(2)– group, the mol­ecule is not quite planar. In the crystal structre, strong N—H⋯O hydrogen b...

Sumario:The title compound, C(17)H(15)NO(2), was prepared from 1-hydroxy­carbazole and 3,3-dimethyl­acrylic acid with a mixture of AlCl(3) and POCl(3) as the cyclization catalyst. Owing to the presence of the –CMe(2)– group, the mol­ecule is not quite planar. In the crystal structre, strong N—H⋯O hydrogen bonds and weaker C—H⋯π inter­actions occur, and a slipped π–π stacking inter­action [centroid–centroid separation = 3.8425 (8) Å] is also observed.
