Abstract

A reaction of 1-TMS-1,2-epoxyoctan-3-ol with NaDMSO-d5 (Na+ CD3S(O)CD2), prepared in situ from DMSO-d6 and NaH, afforded non-1-ene-1,1-d2-3,4-diol. Both the anti and syn isomers showed similar reactivity and the stereochemistry was preserved. α-Ethoxyethyl ether of the epoxy alcohol was converted to the corresponding mono-ethoxyethyl ether of the 1-ene-3,4-diol. Hydroboration and hydrogenation of the corresponding TBS ethers afforded compounds with the "CH2CD2OH" and "CH2CD2H" groups, respectively.
