Chiral palladium complexes with monoterpenoids oximes
摘要:
Oximes of cis-caran-4-one, 3 alpha- and 3 beta-hydroxycaran-4-ones, cis-verbanone, menthone, and 2 beta-hydroxybornan-3-one have been synthesized. The obtained oximes react with lithium tetrachloropalladate to give new chiral palladium complexes containing mono-or bidentate oxime ligands.

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
