Christopher</dc:creator> <dc:creator>Wallis, John D.</dc:creator> <dc:date>2013-01-01</dc:date> <dc:description>The cyclic thionocarbamate of alaninol undergoes nucleophilic attack by sulfur nucleophiles at 5-C to give 1-thiopropyl-2-amine derivatives when derivatised on nitrogen with a Boc group. Iodide under microwave conditions causes a rearrangement to the isomeric thiazolidinone, while "hard" nucleophiles react at the thione group to yield a variety of product types by subsequent C-N or C-O cleavage. X-ray crystallography studies showed that the N-Boc group reduces delocalisation of electron density from nitrogen into the thione group, and thus promotes activation of the ring to nucleophilic attack.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/15111</dc:identifier> <dc:identifier>oai:zenodo.org:15111</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>RSC ADVANCES 3(47) 24997-25009</dc:source> <dc:title>Activation and regioselectivity of five-membered cyclic thionocarbamates to nucleophilic attack</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
