Reaction of 2 , 5 - Disubstituted - l , 3 , 4 - oxadiazoles
Some 5-aryl-2-mercapto-1,3,4-oxadiazole (I) reacted with maleic anhydride, maleic acid and p-benzoquinone affording 2-(5-aryl-1,3,4-oxadiazol-2-ylthio)succinic anhydrides (II), 2-(5-aryl-1,3,4-oxadiazol-2-ylthio)succinic acids (III) and 2-(2,5-dihydroxyphenylthio)-5-aryl-l,3,4-oxadiazoles (IV), respectively. Treatment of 2-methylthio-5-phenyl-l,3-oxadiazole (V) with amines gives 2-[(alkyl or ar...
متن کاملAffinity labeling of alanine aminotransferase by 3-chloro-L-alanine.
The pyridoxal form of alanine aminotransferase from pig heart catalyzes the a,/? elimination reaction with 3chloro-L-alanine as the substrate to form equimolar amounts of pyruvate, ammonia, and chloride. The maximum rate of the a,/3 elimination reaction was 2.5 pmol/min/mg at pH 7.0 (25”(Z), approximately 0.5% that of the transamination reaction between L-alanine and 2-oxoglutarate. Time-depend...
متن کاملN-[(2S)-4-Chloro-2-(l-menthyloxy)-5-oxo-2,5-dihydro-3-furyl]-l-alanine
The title compound, C(17)H(26)ClNO(5), was prepared via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)--one and l-alanine in the presence of potassium hydroxide. The five-membered furan-one ring is approximately planar while the six-membered menth-yloxy ring adopts a chair conformation. The crystal packing is stabilized by inter-molec...
متن کاملSynthesis and Antimicrobial Activity of Some 2-[(4-Substituted-Phenyl-3-Chloro-Azetidin-2-One)-5-(2'-Methylamino-4-Phenyl-1', 3'-Thiazolyl-]-1, 3,4-Thiadiazoles
A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کاملPhenyl 3-methoxy-4-phenoxybenzoate
In the title mol-ecule, C(20)H(16)O(4), the two outermost phenyl rings form dihedral angles of 79.80 (7) and 69.35 (7)° with the central benzene ring. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into ribbons propagating along [1[Formula: see text]0].
