rac-Dimethyl 5-oxo-2-[(2,4,4-trimethyl­pentan-2-yl)amino]-4,5-dihydro­pyrano[3,2-c]chromene-3,4-dicarboxyl­ate

The title compound, C(24)H(29)NO(7), is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The coumarin ring system and the fused pyran ring make a dihedral angle of 10.46 (8)°. A short intra­molecular N—H⋯O hydrogen bond between the amino group and the vicinal...

Sumario:The title compound, C(24)H(29)NO(7), is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The coumarin ring system and the fused pyran ring make a dihedral angle of 10.46 (8)°. A short intra­molecular N—H⋯O hydrogen bond between the amino group and the vicinal carbonyl group generates an S(6) ring. Inter­molecular C—H⋯O inter­actions contribute to the stability of the crystal structure.
