Application of 4739-94-0,When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. In a document type is Article, and a compound is mentioned, 4739-94-0, Name is Ethyl 2,3-dihydrobenzo[1,4]dioxine-2-carboxylate, introducing its new discovery.
The affinity of ligands for either the 5-HT2A or 5-HT2C agonist binding site was enhanced by modification of the 2,5-oxygen substituents that are found in typical hallucinogenic amphetamines such as 4b (DOB). Restriction of the conformationally flexible 2,5-dimethoxy substituents into fused dihydrofuran rings generally resulted in increased potency relative to the parent 2,5-dimethoxy compounds. The pure enantiomers of these arylalkylamines were obtained by enantiospecific synthesis that involved acylation of the heterocyclic nucleus 7 with N-trifluoroacetyl-protected D- or L-alanyl chloride, followed by ketone reduction and N-deprotection. The enantiomers demonstrated modest stereoselectivity at the two receptors. Several general trends within these classes of new compounds were observed during their pharmacological investigation. For most pairs of optical isomers tested, the R-enantiomers of the compounds containing heterocycle 7 bound with only slightly higher affinity than their S-antipodes at the 5-HT2A and 5-HT2C receptors. Likewise, functional studies indicated that the R-enantiomers generally displayed increased potency compared to the S-enantiomers. Aromatization of the dihydrofuran rings of these arylalkylamines further increased affinity and potency. Only a few compounds were full agonists with most of them possessing intrinsic activities in the range of 60-80%. These compounds with a fully aromatic linear tricyclic nucleus are some of the highest-affinity ligands for the 5-HT2A receptor reported to date.
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.Application of 4739-94-0, you can also check out more blogs about4739-94-0
