Rac-Diethyl 5-oxo-2-[(2,4,4-trimethyl-pentan-2-yl)amino]-4,5-dihydro-pyrano[3,2-c]chromene-3,4-dicarboxyl-ate.

ABSTRACT: The title compound, C(26)H(33)NO(7), comprises a racemic mixture of asymmetric mol-ecules containing one stereogenic centre. The dihedral angle between the mean planes of the fused pyran ring and the coumarin ring system is 8.12?(14)°. The mol-ecular structure features a short N-H?O contact, which generates an S(6) ring motif. The crystal packing are stabilized by C-H?O inter-actions.

Project description: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 intra-molecular N-H⋯O hydrogen bond between the amino group and the vicinal carbonyl group generates an S(6) ring. Inter-molecular C-H⋯O inter-actions contribute to the stability of the crystal structure.

rac-Dimethyl 2-(tert-butyl-amino)-5-oxo-4,5-dihydro-pyrano[3,2-c]chromene-3,4-dicarboxyl-ate.

Project description:The title compound, C(20)H(21)NO(7), is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The mol-ecular framework is somewhat bent; the coumarin moiety and the pyran ring are inclined by 7.85 (5)°. The mol-ecular structure is characterized by an intra-molecular N-H⋯O hydrogen bond, which generates an S(6) ring motif, and the crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds. The 3-carboxyl-ate O atom is involved in both of them, having a bifurcated character.

Diethyl 2,3-dihydro-thieno[3,4-b]-1,4-dioxine-5,7-dicarboxyl-ate.

Project description:The title compound, C(12)H(14)O(6)S, is a dicarboxylic acid diethyl ester of 3,4-ethyl-enedioxy-thio-phene, which is a component of electrically conductive poly(3,4-ethyl-enedioxy-thio-phene) (PEDOT). The ethyl-ene group is disordered over two sites with occupancy factors 0.64 and 0.36. Both the carbonyl groups are coplanar with the thio-phene ring. The mol-ecules form centrosymmetric dimers with an R(2) (2)(12) coupling by inter-molecular C-H⋯O hydrogen bonds [3.333 (5) Å] at the ethoxy-carbonyl groups. The dimer units are arranged to form a ribbon-like mol-ecular sheet.
