Abstract

Saffloneoside (1), a structurally unusual p-hydroxycinnamylcyclopentenone C-glucoside obtained from the florets of Carthamus tinctorius, was synthesized on a gram scale in seven steps. A stereospecific acyloin ring contraction controlled by the chirality of glucose moiety at the C5 position of highly substituted cyclohexadienones was discovered. The possible β-orientation hydrogen migration mechanism in the transformation of C5(sp2) into C5(sp3) was proposed.
