outstanding yields. These imidate hydrochlorides proved to be excellent intermediates for an easy transformation to chiral amides in good yields and enantiomeric excess upon simple heating in chloroform. Hydrolysis of the α-benzylated imidate hydrochlorides afforded the corresponding chiral esters with >95% ee.
