Diversity-oriented Synthesis of Spiropyrrolo[1, 2-a]isoquinoline Derivatives via Diastereoselective and Regiodivergent Three-component 1,3-Dipolar Cycloaddition Reactions: In vitro and in vivo Evaluation of the Antidiabetic Activity of Rhodanine Analogues
An efficient diastereoselective route is developed to get access to novel spiropyrrolo[1,2-a]isoquinoline-oxindole skeletons by a one-potthree-component [3 + 2] cycloaddition reaction of (Z)-5-arylidene-1,3-thiazolidine-2,4-diones, isatin derivatives, and 1,2,3,4-tetrahydroisoquinoline (THIQ). ...
4,4″-Dichloro-4′-(2-thienyl)-2,2′:6′,2″-terpyridine

4′-(N-(Propan-1,2-dienyl)pyrrol-2-yl)-2,2′:6′,2″-terpyridine
A new pyrrole-substituted terpyridine derivative that possesses an allene moiety was obtained as an “unexpected” sole product during an attempt to alkylate the N-atom of pyrrole with propargyl bromide in order to obtain an alkyne-functionalized terpyridine.
