3-Methyl-2-propionamido-butanoic acid.

ABSTRACT: The reaction of propionyl isothio-cyanate with valine was found to give the title compound, C(8)H(15)NO(3), instead of the expected thio-urea product. The whole mol-ecule is non-planar and the carbonyl group is cis to the methyl-butanoic acid group across the C-N bond. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonds build up a two-dimensional network developing parallel to (100).

2-(2,5-Dichloro-benzene-sulfonamido)-3-methyl-butanoic acid.

Project description:The structure of the title compound, C(11)H(13)Cl(2)NO(4)S, shows one sulfonamide-O atom to lie almost in the plane of the benzene ring [C-C-S-O = -178.7?(2) °] and the other to one side [C-C-S-O = -49.4?(3)°]. Lying to the other side is the amine residue, which occupies a position almost perpendicular to the plane [C-S-N-C = 70.2?(2)°]; the carb-oxy-lic acid group is orientated to lie over the benzene ring. In the crystal, the appearance of an 11-membered {?OH?OCOH?OC(2)NH} synthon, which features the hy-droxy group forming both donor (to a carbonyl-O) and acceptor (from the amine-H) inter-actions, leads to the formation of a supra-molecular chain along the a axis. Chains are connected in the crystal structure by C-H?O contacts.

2-(4-Acetamido-benzene-sulfonamido)-3-methyl-butanoic acid.

Project description:In the title compound, C(13)H(18)N(2)O(5)S, the benzene ring and the acetamide group are almost coplanar [dihedral angle = 5.6?(3)°], and the amine group projects almost vertically from this plane [C-C-S-N = -84.5?(7)°]. A short intra-molecular C-H?O contact occurs. In the crystal, O-H?O, N-H?O and N-H?(O,O) hydrogen bonds lead to a three-dimensional network. One of the methyl groups of the isopropyl residue is disordered over two orientations in a 0.747?(16):0.253?(16) ratio.

4-(Methyl-sulfan-yl)-2-(p-toluene-sulfonamido)butanoic acid.

Project description:In the title compound, C(12)H(17)NO(4)S(2), the carboxyl groups link the mol-ecules into centrosymmetric dimers through O-H?O hydrogen bonds. An N-H?O hydrogen bond between the NH group of the l-methio-nine unit and a neighbouring carboxyl group, together with a complementary C-H?O contact to one O atom of the sulfonyl group, link the dimers into one-dimensional chains along the crystallographic b axis.

4-(3-Fluoro-4-methyl-anilino)-2-methyl-idene-4-oxo-butanoic acid.

Project description:The title compound, C12H12FNO3, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the 3-fluoro-4-methyl-phenyl ring and the oxo-amine group is 25.7?(7)° in mol-ecule A and 71.3?(7)° in mol-ecule B, while the mean plane of the 2-methyl-idene-4-oxo-butanoic acid group is twisted by 76.2?(1)° from that of the oxo-amine group in mol-ecule A and by 76.2?(4)° in mol-ecule B. In the crystal, N-H?O and O-H?O hydrogen bonds [the latter forming an R 2 (2)(8) graph-set motif] link the mol-ecules into a two-dimensional network parallel to the ac plane.

4-(4-Iodo-anilino)-2-methyl-ene-4-oxo-butanoic acid.

Project description:In the title compound, C11H10INO3, an addition product of itaconic acid anhydride and 4-iodo-aniline, the least-squares planes defined by the atoms of the aromatic moiety and the non-H atoms of the carb-oxy-lic acid group enclose an angle of 74.82?(11)°. In the crystal, classical O-H?O hydrogen bonds formed by carb-oxy-lic groups, as well as N-H?O hydrogen bonds formed by amide groups, are present along with C-H?O contacts. Together, these connect the mol-ecules into dimeric chains along the b-axis direction.

(2R)-2-(1,3-Dioxoisoindolin-2-yl)-4-(methyl-sulfan-yl)butanoic acid.

Project description:The title compound, C(13)H(13)NO(4)S, the 1,3-dioxoisoindolin-2-yl unit is planar (r.m.s. deviation 0.0192?Å) and is oriented at a dihedral angle of 79.14?(18)° to the carboxyl-ate group. An intra-molecular C-H?O hydrogen bond leads to the formation of a planar (r.m.s. deviation 0.0419?Å)R(5) ring motif. In the crystal, mol-ecules are connected through O-H?O and C-H?O hydrogen bonds with R(2) (2)(9) ring motifs into chains extending along the b axis.

4-[(4-Bromo-phenyl)amino]-2-methyl-idene-4-oxo-butanoic acid.

Project description:In the title compound, C11H10BrNO3, two independent mol-ecules (A and B) crystallize in the asymmetric unit. The dihedral angles between the mean planes of the 4-bromo-phenyl ring and amide group are 24.8?(7) in mol-ecule A and 77.1?(6)° in mol-ecule B. The mean plane of the methyl-idene group is further inclined by 75.6?(4) in mol-ecule A and 72.5?(6)° in mol-ecule B from that of the amide group. In the crystal, N-H?O hydrogen bonds formed by amide groups and O-H?O hydrogen bonds formed by carb-oxy-lic acid groups are observed and supported additionally by weak C-H?O inter-actions between the methyl-idene and amide groups. Together, these link the mol-ecules into chains of dimers along [110] and form R 2 (2)(8) graph-set motifs.

4-[(4-Acetyl-phen-yl)amino]-2-methyl-idene-4-oxo-butanoic acid.

Project description:In the title compound, C13H13NO4, the N-C(=O) bond length of 1.354?(2)?Å is indicative of amide-type resonance. The dihedral angle between the mean planes of the benzene ring and oxo-amine group is 36.4?(3)°, while the mean plane of the 2-methyl-idene group is inclined by 84.2?(01)° from that of the oxo-amine group. In the crystal, classical O-H?O hydrogen bonds formed by the carb-oxy-lic acid groups and weak N-H?O weak inter-actions formed by the amide groups and supported by weak C-H?O inter-actions between the 2-methyl-idene, phenyl and acetyl groups with the carb-oxy-lic acid, oxo-amine and acetyl O atoms, together link the mol-ecules into dimeric chains along [010]. The O-H?O hydrogen bonds form R 2 (2)(8) graph-set motifs.

(2R)-2-(1,3-Dioxoisoindolin-2-yl)-3-methyl-butanoic acid.

Project description:In the title compound, C(13)H(13)NO(4), the dihedral angle between the nine-membered phthalimino ring system and the carb-oxy-lic acid group is 67.15?(9)°. An intra-molecular C-H?O close contact, which forms an S(6) ring, may help to establish the mol-ecular conformation. In the crystal, mol-ecules are linked by O-H?O hydrogen bonds, thereby forming C(7) chains propagating in [010].

Crystal structure of (R,S)-2-hy-droxy-4-(methyl-sulfan-yl)butanoic acid.

Project description:The title compound, a major animal feed supplement, abbreviated as HMTBA and alternatively called dl-me-thio-nine hy-droxy analogue, C5H10O3S, (I), was isolated in pure anhydrous monomeric form. The melting point is 302.5?K and the compound crystallizes in the monoclinic space group P21/c, with two conformationally non-equivalent mol-ecules [(I A ) and (I B )] in the asymmetric unit. The crystal structure is formed by alternating polar and non-polar layers running along the bc plane and features an extensive hydrogen-bonding network within the polar layers. The Hirshfeld surface analysis revealed a significant contribution of non-polar H?H and H?S inter-actions to the packing forces for both mol-ecules.
