Biomimetical
catalysis of hydrolysis of a-amino
acids esters promoted by chiral palladacycles
Abstract
Insertion of sterically bulked substituents in
cyclopalladated arylamines which are used as catalysts of hydrolysis of
optically active amino acids ethers leads to difference of catalytic rate
constants of hydrolysis of enantiomeric pairs up to 4.5 times. Unexpected
effect of "reversion" of stereoselectivity of catalyst in dependence on
bulkiness of substituents at palladacycle’s б-carbon atom was observed
