Ring Chain Transformations. XIV. 3-(omega-Aminoalkyl)-1,2,4-triazoles by Reaction of Isothiosemicarbazides with Lactam Acetals or Lactim Ethers

Isothiosemicarbazide hydrohalides 1 react with lactam acetals 2 or lactim ethers 3 by the formation of lactamisothiosemicarbazones 4 or ring transformed 3-(omega-aminoalkyl)-1,2,4-triazoles 6.The latter can independently by synthesized by alkylation of lactamthiosemicarbazones 9.Condensation of primary 3-(omega-aminoalkyl)-1,2,4-triazoles 6 with lactim ethers 7 can lead to 3-lactamiminoalkyl-1,2,4-triazoles 8.

Cyclic amidine analogues of taurine and homotaurine: Synthesis and effects on rat skeletal muscle

A series of amidinosulfonic acids IIIa-f, analogs of taurine and homotaurine, was synthesized by reacting 2-aminoethane or 3-aminopropane sulfonic acid with lactim ethers Ia-c and then cyclized to sultams IVa-c and Vd-f. The effects of some selected amidinosulfonic acids III on membrane ionic conductances of rat skeletal muscle are described.

A Novel Class of “GABAergic” Agents: 1-Aryl-3-(aminoalkylidene)oxindoles

Antagonism of mercaptopropionic acid (MPA) induced convulsions, reflecting a GABAergic mechanism, was observed in a series of 1-aryl-3-(aminoalkylidene)oxindoles.Optimal MPA antagonism was associated with 3-halo, 3-alkyl, and/or 4-alkoxy substituents in the pendant aryl ring and with (dimethylamino)methylene, 1-(dimethylamino)ethylidene and N-methyl-2-pyrrolidinylidene side chains.The precise mechanism of action of these agents is unclear at this time; however, they are not GABA mimics and they do not affect GABA levels.Like other GABAergic agents, these compounds are potent enhancers of benzodiazepine binding and they antagonize cyclic GMP elevations induced by isoniazid.Compounds from this series may therefore have potential therapeutic utility as anticonvulsants or anxiolytics.

1-Aza-2-azoniaallene salts: Reactions with azomethines and other N-nucleophiles

Azomethines undergo nucleophilic addition to 1-aza-2-azoniaallene salts 7 to furnish N-(azoalkyl)iminium salts (e.g. 10, 12, 13). With cyclic hydrazones such as pyrazole or indazole, heterocumulenes 7 afford bicyclic 1,2,4,5-tetrazinium salts (e.g. 14, 16), or simple N-adducts such as 15, 17. On the other hand, with open-chain hydrazones azinium salts 19 are formed. Benzotriazole and the aziridine 21 react with 1-aza-2-azoniaallene salts 7 to afford (azoalkyl)ammonium salts 20, 22. The heterocumulenes 7 undergo cycloaddition across the C=N double bond of the azirine 23 to furnish azirenotriazolium salts 25, while with the 1-aza-2-azoniaallene salt 3a the triazolium salt 28 was formed. The constitutions of compounds 22, 25a and 28 were confirmed by X-ray structural analyses.

Synthesis and Reactivity of Polyamines: Part 3 – 2,5-Bis-omega-aminoalkylpyrazines and Piperazines

The nitroenamines (1) and (3) on catalytic reduction under acid conditions give rise to the pyrazines (2) and (4) respectively.The pyrazines (2) can be further hydrogenated to the piperazines (10) which show structural similarity to the naturally occuring polyamine, spermine (11).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 5264-35-7, you can also check out more blogs about5264-35-7

A simple methodology for [1,2-A]-fused tricyclic dihydroquinolines is established. The key ste of the methodology is an intramolecular Buchwald-Hartwig amination reaction of suitabl halogenated (both bromo and chloro) cyclic enaminoketones, enaminoesters and enaminonitrile with various ring size (from five-to seven-membered). Optimal reaction conditions (palladiu source, base, ligand) depend on the ring size of the starting enamine, giving 65-98% yield of th tricyclic product. A treatment of the products with perchloric acid gives respective quinoliniu perchlorates.
