A variety of alpha-bromonitroalkenes and 1,3-dicarbonyl compounds were allowed to react under optimized conditions, in the presence of a bifunctional quinine-derived sterically encumbered squaramide (H-bond donor) organocatalyst. The conditions developed in this article have great advantages over the methods known in the literature in terms of reaction duration (1-6 h vs. 24-96 h) and reaction temperature (room temperature vs. -20 degrees C to -50 degrees C) giving rise to quite diastereoselective products with good enantioselectivities up to 97% ee.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/233362</dc:identifier> <dc:identifier>oai:aperta.ulakbim.gov.tr:233362</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>NEW JOURNAL OF CHEMISTRY 46(2) 599-606</dc:source> <dc:title>Enantioselective synthesis of 2,3-dihydrofurans using a bifunctional quinine/squaramide organocatalyst</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
