Allyl protecting group and more commonly used benzyl protecting group were easily introduced in several (cyclo)alkyl α-hydroxycarboxylic acids through a modified Steglich esterification using O-allyl or O-benzyl-N,N’-dicyclohexylisoureas. Corresponding esters were prepared under mild conditions and short reaction times; high reaction yields and easy purification of final products favored this procedure. Complete unambiguous assignment for 1 H and 13C-NMR data for prepared compounds is given.
