Crystal structure of 3-benzyl-1-[(cyclohexylidene)amino]thiourea
The conformation of the title compound, C14H19N3S, is partially determined by an intra-molecular N-H⋯N hydro-gen-bond inter-action, although the N-H⋯N angle of 108° is quite small. The cyclo-hexyl-idene ring has a chair conformation and its mean plane is inclined to the benzene ring by 46.30 (8)°. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers, ...
متن کاملBenzyl N-[(Z)-(1-methyl-2-sulfanylpropylidene)amino]carbamodithioate
The title compound, C(12)H(16)N(2)S(3), was obtained by the condensation reaction of S-benzyl dithio-carbazate and 3-mercaptobutan-2-one. The phenyl ring and thiol (SH) group are approximately perpendicular [S-C-C-C and N-C-C-S torsion angles = 67.8 (3) and 116.9 (2)°, respectively] to the rest of the mol-ecule. In the crystal, mol-ecules are linked by weak S-H⋯S and N-H⋯S hydrogen bonds, π-π i...
متن کامل(S)-Benzyl 2-amino-3-(4-hydroxyphenyl)propanoate
The title compound, C(16)H(17)NO(3), adopts a folded conformation in the crystal structure. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions. The absolute configuration was assigned assuming that the absolute configuration of the starting material l-tyrosine was retained during the synthesis.
متن کاملSynthesis of 2-amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine.
2-Amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine (2), a precursor of Watasenia preluciferin (coelenterazine) (1), is widely distributed in marine bioluminescent animals. It was prepared from p-hydroxyphenylglyoxal aldoxime (5) in two steps; by condensation with or-aminophenylpropiononitrile in the presence of TiCl4 in pyridine, followed by reduction of the resulting N-oxide (6) with Zn-AcOH in CH2C...
