Synthesis, Reactions and Antibacterial Activity of 3-Acetyl[1,2,4]triazolo[3,4-a]isoquinoline Derivatives using Chitosan as Heterogeneous Catalyst under Microwave Irradiation

In this paper we present a study of the stirring effect on the transient regimes in the BZ reaction catalyzed by ferroin in a batch. Our experiments show that the stirring rate

To prove and affi rm the role and importance of indole derivatives as hyaluronidase inhibitors, a new series of aminomethyl indole derivatives (AMIDs) were tested for the

The latter condenses with active methylene compounds to yield pyridazine derivatives, and with hydroxylamine hydrochloride to produce oxadiazole and 1,2,3-triazole derivatives.

In refluxing aque- ous acetic acid and in the presence of sodium acetate, compound 6 reacted with hydroxylamine hydrochlo- ride to yield 2-arylhydrazononitrile 12 , formed via

1,3-Dipolar cycloaddition of azomethine ylides derived from acenaphthylene-1,2-dione and 5- methyl-benzo[b]-thiophene-2,3-dione with L-proline, thiazolidine-4-carboxylic acid

Hydrolysis of this compound leads to a spirocyclic dititanoxane with a short linear Ti-O-Ti bond and pentacoordinated Ti centers carrying two Cl atoms each. The palladium compound 16

Beckmann rearrangement has however been achieved for 3-benzoyl(O-ethyloxime)-6-phenylpyridazine (5a) and oxime 4 giving solely 3-carboxanilide-6-phenylpyridazine

All derivatives of 4-acetyl-4-phenylpiperidine except one com- pound exhibited more or less protection against mice writhing, whereas all the compounds proved to be inactive in
