The enantioselective synthesis of (+)-eutypoxide B, a metabolite isola
ted from the culture medium of the fungus Eutypa Lata, is described. T
wo highly stereoselective and efficient sequencial 1,4-additions to en
one systems, derived from D-(-)-quinic acid, are the key to the synthe
sis. The synthesis of a diastereoisomer of (+)-eutypoxide B, was also
accomplished.
