Oxidation with the less expensive DEAD typically produced small amounts (≤ 5%) of products of carboethoxy transfer to the hydrazine. Oxidation with MTAD was more rapid and could be carried out at lower temperature (−78 °C). Yields with each reagent were roughly comparable and both led to complete reaction within 5 min at 0 °C.

Alcohol 8 was synthesized as follows: Reaction of cyclohexene oxide with the 1:1 complex of boron trifluoride etherate and the lithiated tetrahydropyranyl ether of propargyl alcohol in tetrahydrofuran at −78 °C produced the trans-cyclohexanol in 82% yield

Silylation with t-butyldimethylsilyl chloride-4-dimethylaminopyridine-triethylamine and selective removal of the tetrahydropyranyl protecting group with hydrogen peroxide-trichloroacetic acid in t-butyl alcohol-methylene chloride, then furnished alcohol 8 in 70% yield for the two steps. Other methods for removal of the tetrahydropyranyl protecting group induced competitive desilylation.
