Coulomb Explosion Imaged Cryptochiral ( R, R)-2,3Dideuterooxirane: Unambiguous Access to the Absolute Configuration of (+)- Glyceraldehyde

The absolute configuration of (R,R)-2,3-dideuterooxirane, which has been independently determined using Coulomb explosion imaging, has been unambiguously chemically correlated with the stereochemical key reference (+)-glyceraldehyde. This puts the absolute configuration of D(+)-glyceraldehyde on firm experimental grounds.
