Synthesis of α- and β-D,L-ribo-carbahex-2-ulofuranose

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.

Synthesis of pseudo-Ribofuranoses by Stereocontrolled Reactions on 4-Hydroxycyclopent-2-enylmethanol Derivatives

The diol 3 is a major product formed from a Prins reaction on cyclopentadiene and was readily converted into the derivatives 4-7.The latter compounds were obtained in states of high optical purity by using both enzyme-catalysed hydrolysis and esterificati
