Abstract A route to the functionalised cyclopentenone derivative,(2S)-(23)-dibenzyloxy-5- (hydroxymethyl) cyclopentene-4-enone ethylene acetal, has been developed from a deoxyinosose that is readily accessible. The carbocyclisation procedure was less efficient in affording (2S)-(2, 34, 5)-2, 3, 4, 5-tetrahydroxy-2, 3-O-isopropylidenecyclohexanone from 6- deoxy-1, 2: 3, 4-di-O-isopropylidene-β-l-arabino-hex-5-enopyranose. Various reactions ...
