comparison of the 1HNMR spectra of the tris-(R)- and the tris-(S)-MPA ester derivatives. An experimental demonstration of this correlation with 24 triols of known absolute configuration and a protocol using two parameters-Deltadelta(RS)(H3) and the difference between Deltadelta RS (H2) and Deltadelta RS (H3) = absolute value (Delta(Deltadelta RS))-for its application to the determination of the absolute

derivatives or mirror image deoxyribonucleosides (l-deoxyribonucleosides) from d-ribose is reported. Starting from inexpensive d-ribose, an acyclic d-form carbohydrate precursor was synthesized to study a unique carbonyl translocation process. In this novel radical reaction, not only was the configuration of the sugar transformed from the d-form to the l-form, but also deoxygenation at the C(2) position

A synthesis of (S)-manoalide diol (2a) has been achieved using 2-deoxy-D-ribose as starting material to unequivocally supply the stereochemistry. Reduction of natural manoalide afforded enantiomeric manoalide diol 2b. Thus, the absolute configuration of manoalide is R (as depicted in 1).

that is, the resolvins, are excellent candidates displaying such bioactions. The first totalsynthesis of the specialized pro-resolving mediator RvD1n-3 DPA has been achieved using the underutilized sp3 -sp3 Negishi cross coupling reaction and an alkyne hydrosilylation-protodesilylation protocol. Biologicalevaluations revealed that this novel mediator displays low nanomolar pro-resolving properties and
