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

ABSTRACT: 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.

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.
