Even sterically demanding substrates could be coupled to afford the corresponding pinacols in good yields. Systematic studies concerning the origin of the diastereoselectivities led to the proposal of a mechanism for this synthetically useful reaction. Acroleins with α-branched alkyl side chains were coupled to give the corresponding syn pinacols, while on the other hand, acroleins with less bulky substituents furnished the anti derivatives. The effects of both the substrates and the reagents on the diastereo- and enantioselectivities were investigated. An unexpected catalytic formation of cyclopropanols was found.</dcterms:abstract> <dc:creator>Jung, Marc</dc:creator> <dcterms:available rdf:datatype="">2011-03-24T18:16:17Z</dcterms:available> <dcterms:issued>2005</dcterms:issued> <dcterms:bibliographicCitation>First publ. in: Chemistry - A European Journal 11 (2005), 10, pp. 3127-3135</dcterms:bibliographicCitation> <bibo:uri rdf:resource=""/> <dcterms:rights rdf:resource=""/> <dc:creator>Vogel, Till</dc:creator> <dc:language>eng</dc:language> <dc:rights>deposit-license</dc:rights> <dc:creator>Groth, Ulrich</dc:creator> <dc:contributor>Jung, Marc</dc:contributor> <dc:contributor>Vogel, Till</dc:contributor> <dc:contributor>Groth, Ulrich</dc:contributor> <dc:date rdf:datatype="">2011-03-24T18:16:17Z</dc:date> <dc:format>application/pdf</dc:format> </rdf:Description> </rdf:RDF>
