Synthesis of α- and β-D,L-ribo-carbahex-2-ulofuranose
Marschner,Penn,Griengl
, p. 5067 - 5078 (2007/10/02)
Both α- and β-D,L-ribo-carbahex-2-ulofuranose have been synthesized in racemic form starting from norbornen-2-one. In the course of the synthesis the reaction of sulfur ylides with α-alkoxyketones took an unexpected stereochemical pathway.
