Dantanarayana, Anura P.; DuPre, Brian; May, Jesse A.; Lynch, Vincent M. published their research in Journal of Heterocyclic Chemistry on February 28 ,1999. The article was titled 《A convenient synthesis of the novel 5H-thieno[2,3-e]-4,1,2-oxathiazepine ring system via an alkoxycarbenium ion intermediate》.Name: 2-(Thiophen-3-yl)-1,3-dioxolane The article contains the following contents:
3-(Methoxymethoxymethyl)-2-thiophenesulfonamides and 3-hydroxymethyl-N-methoxymethyl-2-thiophenesulfonamides were shown to undergo cyclization when treated under anhydrous acidic conditions to provide a novel 2,3-dihydro-5H-thieno[2,3-e]-4,1,2-oxathiazepine ring system. Incorporation of a primary sulfonamide group into position seven of the mol. provided compounds which inhibit human carbonic anhydrase II. In the part of experimental materials, we found many familiar compounds, such as 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Name: 2-(Thiophen-3-yl)-1,3-dioxolane)
2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3) is one of dioxolane. 1,3-Dioxolane derivatives are recognized as important motifs for the construction of numerous pharmacologically active molecules as antiviral, antifungal, anti-HIV, and adrenoreceptor antagonists.Name: 2-(Thiophen-3-yl)-1,3-dioxolane
