Ethyl 2-amino-7,7-dimethyl-2′,5-dioxospiro[5,6,7,8-tetrahydro-4H-chromene-4,3′(2′H)-1H-indole]-3-carboxylate

In the molecule of the title compound, C(21)H(22)N(2)O(5), the indole system and the spiro-pyran ring are almost planar [maximum deviations of 0.0447 (17) and 0.0781 (17) Å, respectively]; the dihedral angle between them is 84.6 (3)°. The remaining six-membered ring adopts a twisted conformation. I...
