- On the formation of reductic acid from pentoses or hexuronic acids
-
Careful hydrolysis of (±)-cis- or (±)-trans-tetrahydro-2,5-dimethoxy-2-furaldehyde dimethyl acetal proceeded via 5,5-dimethoxy-4-oxopentanal to give (±)-trans-4-hydroxy-5-methoxy-2-cyclopenenone and (±)-trans-4,5-dihydroxy-2-cylopentenone. The latter product did not isomerize to 2,3-dihydroxy-2-cyclopentenone (reductic acid) on prolonged reaction.
