The Enantioselective Synthesis of Marmelo Oxides A and B and the Assignment of the Absolute Configurations of Marmelo Oxides

(+)-Marmelo oxide A and (-)-marmelo oxide B were stereoselectively synthesized form D-glutamic acid via (-)-marmelo lactones A and B.The absolute configurations of marmelo oxides were thus determined to be the (+)-oxide A having the (2R,4R) and (+)-oxide B having (2S,4R) configuration.

A NOVEL SYNTHESIS OF DL-MARMELOLACTONE AND DL-ROSE OXIDE BY ELECTROCHEMICAL OXYSELENENYLATION SEQUENCE

One-step transformation of olefins 1 into allylic alcohols and ethers 3 has been accomplished by electrooxidative oxyselenylation-deselenenylation sequence.The electrochemical process furnished efficient syntheses of dl-marmelolactone 4 and dl-rose oxide 5.
