menthone oxime ethers were synthesized in three steps starting from (–)-menthol. Analysis of the 13C NMRchemical shift differences between α carbons of oxime derivatives (O-alkyl oximes) provides a convenient and reliable means of assigning oxime stereochemistry. It has been found that carbons syn to the oxime are shifted more upfield than carbons anti to the oximemoiety. Significant E products were
