Stereoselective Synthesis of (E)-2-Hydroxyimino-2-phenylacetonitrile by Photolysis of 4-Azido-3-phenylfurazan 2-Oxide

design and synthesis of novel (e)-2-(4-fluorophenyl)-2-(hydroxyimino)-1-(2-(methylthio)pyrimidin-4-yl)ethanone as potential protein kinase inhibitors and identifying cytotoxic effect

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...

SYNTHESIS OF OXAZOLO [3, 2-b] 1, 2, 4- TRIAZINES A NOVEL HETEROCYCLIC SYSTEM

The synthesis of 6- methyl- 2- phenyl- 7H- oxazolo [3,2-b] 1,2,4-Triazine- 7-one (6, R=Ph) and its 2-P- bromophenyl analogue to the two members of a new heterocyclic system is described

A Simple Method for the Preparation of Cis-(3-Azido-4-Styryl)-2-Azetidinone

The synthesis of the title compound is described. Deprotection of Cis(N-Trityl-3-azido-4-Styryl)-2-azetidinone to Cis-(3-azido-4-styryl)-2-azetidinone was found to be accelerated by the special salt effect under acidic condition

(E)-2-{4-[1-(Hydroxyimino)ethyl]phenyl­iminomethyl}-6-methoxyphenol mono­hydrate

In the title compound, C(16)H(16)N(2)O(3)·H(2)O, the benzene rings are nearly coplanar with each other, forming a dihedral angle of 4.46 (3)°. There is a strong intra-molecular O-H⋯N hydrogen bond which results in a six-membered ring. In the crystal, the mol-ecules are connected into a three-dimensional network via O-H⋯O and O-H⋯N inter-molecular hydrogen bonds, forming a centrosymmetric ring a...
