A diastereocontrolled route to conduritols A-F has been developed starting from a commonchiralbuildingblock containing an oxabicyclo[3.2.1]octane framework.
A new stereocontrolledroute to (−)-shikimic acid, the component of the fruit of shikimi tree, Illicium religiosum, and the key biogenetic precursor of a variety of aromatic natural products, has been developed using the chiral 2,5-cyclohexadienol synthon.
Six possible diastereomers of conduritols have been synthesized diastereoselectively in an integrated manner starting from a single chiral precursor, which served as a synthetic equivalent of chiral cis-1,4-dihydroxycyclohexa-2,5-diene.
