1-(2-Oxo-3,4-dihydro-2H-1,3-benzoxazin-4-yl)urea monohydrate.

ABSTRACT: The organic molecule in the title hydrate, C(9)H(9)N(3)O(3)·H(2)O, was obtained by the condenstation of salicylic aldehyde with urea in acetonitrile. The oxazine ring adopts a slightly distorted sofa conformation, with the N atom deviating from the plane passing through the other atoms of the ring by 0.267 (2) Å. The crystal structure displays inter-molecular N-H⋯O and O-H⋯O hydrogen bonding.

Methyl 3-hydr-oxy-4-oxo-3,4-dihydro-2H-1,2-benzothia-zine-3-carboxyl-ate 1,1-dioxide monohydrate.

Project description:In the mol-ecule of the title compound, C(10)H(9)NO(6)S·H(2)O, the benzothia-zine ring adopts an envelope conformation.

2-(2-{[4-Oxo-3-(2-phenyl-eth-yl)-3,4-dihydro-quinazolin-2-yl]sulfan-yl}eth-yl)-2,3-dihydro-1H-isoindole-1,3-dione.

Project description:In the title compound, C(26)H(21)N(3)O(3)S, the quinazolinyl group is essentially planar [r.m.s. deviation for the 10 non-H atoms = 0.057?Å]. The isoindoline-1,3-dione group is linked by an SCH(2)CH(2) chain to the pyrimidinyl C atom that lies between the two N atoms. Also, the phenyl group is linked by a CH(2)CH(2) chain at the N atom adjacent to the carbonyl group. This results in a conformation with these substituents lying to either side of the central quinazolinyl unit, with the former being approximately parallel [dihedral angle = 4.93?(7)°], and the phenyl group being inclined [dihedral angle = 71.61?(9)°] to the central quinazolinyl fused-ring system. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by C-H?O inter-actions, involving all three carbonyl-O atoms, and ?-? inter-actions occurring between the pyrimidinyl and isoindole-benzene rings [inter-centroid distance = 3.5330?(13)?Å].
