Graphical Abstract

Flexible Sequenz: Die Sialinsäure Neu5Ac wurde regio- und stereoselektiv aus einem Glycal über ein [1,2,3]-Oxathiazocan-2,2-dioxid-Intermediat synthetisiert (siehe Schema). Die Reaktionssequenz aus Rh-katalysierter Aziridinierung und Indium-vermittelter Barbier-Allylierung könnte eine flexible Route zu verschiedensten Sialinsäuren bieten, denn das Oxathiazocan war kompatibel mit einer Reihe von Nucleophilen.
