SYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES
Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...
متن کامل4-(3-Fluoro-4-methylanilino)-2-methylidene-4-oxobutanoic acid
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 grou...
متن کامل2-(3-Bromo-4-methoxyphenyl)acetic acid
The title compound C(9)H(9)BrO(3), was synthesized by the regioselective bromination of 4-meth-oxy-phenyl-acetic acid using bromine in acetic acid in a 84% yield. In the mol-ecular structure, the meth-oxy group is almost coplanar with the phenyl ring within 0.06 Å; the acetic acid substituent is tilted by 78.15 (7)° relative to the ring. The C-C-C angles at the OMe, acetyl and Br substituents a...
متن کامل2-(4-Acetamidobenzenesulfonamido)-3-methylbutanoic acid
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 iso...
متن کامل2-Methyl-3-(4-nitrophenyl)acrylic acid
The title compound, C(10)H(9)NO(4), forms R(2) (2)(8) dimers due to inter-molecular O-H⋯O hydrogen bonding in the crystal structure. Two dimers are further linked to each other through two inter-molecular C-H⋯O hydrogen bonds, forming an R(3) (3)(7) ring motif. The nitro groups form an intra-molecular C-H⋯O hydrogen bond mimicking a five-membered ring. As a result of these hydrogen bonds, polym...
