Crystal structure of 3,4-dimethyl 2-(tert-butyl-amino)-5-[2-oxo-4-(thio-morpholin-4-yl)-2H-chromen-3-yl]furan-3,4-di-carboxyl-ate ethyl acetate hemisolvate.

ABSTRACT: In the title hemisolvate, C25H28N2O7S·0.5C4H8O2, the thio-morpholine ring adopts a chair conformation, with the exocyclic N-C bond in an equatorial orientation. The dihedral angle between the coumarin ring system (r.m.s. deviation = 0.044 Å) and the furan ring is 64.84 (6)°. An intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. The ethyl acetate solvent mol-ecule is disordered about a crystallographic inversion centre. In the crystal, the components are linked by C-H⋯O and C-H⋯S hydrogen bonds, generating a three-dimensional network.

2-Oxo-2H-chromen-4-yl 4-tert-butyl-benzoate.

Project description:In the title mol-ecule, C(20)H(18)O(4), the three methyl groups of the tert-butyl substituent show rotational disorder. Each methyl group is split over three positions, with refined site-occupation factors of 0.711?(4), 0.146?(3) and 0.144?(4). The benzene ring of the benzoate group is oriented at a dihedral angle of 60.70?(7)° with respect to the planar chromene ring [maximum deviation = 0.046?(2)?Å]. The crystal structure features centrosymmetric R(2) (2)(8) dimers formed via C-H?O inter-actions, and these dimeric aggregates are connected by C-H?? inter-actions.

tert-Butyl 6-amino-3,4-dihydro-2H-1,4-benzoxazine-4-carboxyl-ate.

Project description:The title mol-ecule, C(13)H(18)N(2)O(3), contains a benzene ring fused to an oxazine ring and one tert-but-oxy-carbonyl group bound to the N atom of the oxazine ring. A weak intra-molecular C-H?O inter-action occurs. In the crystal, inter-molecular N-H?O and C-H?O hydrogen bonds stack the mol-ecules down the b axis. Weak C-H?N contacts connect the stacks, generating a three-dimensional network.

Crystal structure of (tert-butyl-carbamo-yl)(4-chloro-2-oxo-2H-chromen-3-yl)methyl acetate.

Project description:In the title compound, C17H18ClNO5, which was synthesized by reacting 4-chloro-3-formyl-coumarin, acetic acid and tert-butyl isocyanide, the acetamido side chain is convoluted with ring-to-side chain C-C-C-C, C-C-C-N and C-C-N-C torsion angles of -123.30?(14), -135.73?(12) and 176.10?(12)°, respectively. In the crystal, N-H?O and weak C-H?O hydrogen bonds are present, which together with ?-? coumarin-ring inter-actions [ring centroid separations = 3.4582?(8) and 3.6421?(9)?Å], give rise to a layered structure lying parallel to (001).
