A Concise And General Entry into (R)-4-Hydroxy-2-Substituted Cyclopent-2-enones from D-Glucose: Chiral Intermediates for the Synthesis of PGE2, (-)-Pentenomycin I, and Allethrin

A general strategy for the transformation of D-glucose into different (R)-4-hydroxycyclopent-2-enones is described.This has been illustrated by the synthesis of (R)-2--4-hydroxycyclopent-2-enone, (R)-2-benzyloxymethyl-4-hydroxycyclopent-2-enone, and (R)-2-allyl-4-hydroxycyclopent-2-enone, which are potential chiral synthons for prostaglandin E2, the antibiotic (-)-pentenomycin I, and the synthetic insecticide allethrin, respectively.The second chiral synthon was obtained by two different routes, one of them involving a novel palladium(0)-catalysed rearrangement of a vinyloxirane intermediate.

Synthesis of (R)-4-Hydroxy-2-benzyloxymethylcyclopent-2-en-1-one from D-Glucose via Palladium(0)-catalysed Rearrangement of a Vinylic Epoxide Intermediate

The transformation of D-glucose into (R)-4-hydroxy-2-benzyloxymethylcyclopent-2-en-1-one (3), a potential chiral synthon for the antibiotic (-)-pentenomycin I (4), has been achieved via the intramolecular aldolisation-dehydration of the 2-hydroxy-4-oxo-aldehyde (9) which was obtained by two different routes, one of them involving palladium(0)-catalysed rearrangement of a vinylic epoxide intermediate.
