Heterocycles, 65, pp. 2635-2647.1881-0942http://hdl.handle.net/10092/391Intramolecular heterocyclization of (Z)-5-(2-hydroxyethyl)-3-methyl-4-oxothiazolidines, bearing electron-withdrawing groups conjugated to an exocyclic double bond at C(2)-position, afforded under reductive conditions, not easily accessible cis-tetrahydrofuro[2,3-d]thiazole derivatives. The reactions of these functionalized push-pull β-enamines occur in a stereocontrolled fashion via activated vinylogous N-methyliminium ions, which are trapped by an internal hydroxyethyl group.enthiazolidinesvinylogous N-iminium ionheterocyclizationStereocontrolled Synthesis of New Tetrahydrofuro[2,3-d]thiazole Derivatives via Activated Vinylogous Iminium IonsJournal ArticleFields of Research::250000 Chemical Sciences::250500 Macromolecular Chemistry::250501 Synthesis of macromoleculesFields of Research::250000 Chemical Sciences::250500 Macromolecular Chemistry::250502 Physical chemistry of macromolecules
