Racemic tetrazole analogues of N-benzyloxycarbonyl derivatives of alanine, S-benzyl-cysteine, leucine, phenylalanine and valine were resolved by means of L-tyrosine hydrazide. The resolution of tetrazole analogue of N-benzyloxycarbonyl-DL-phenylalanine provided the L-enantiomer. From the other fractionation experiments tetrazole analogues of N-benzyloxycarbonyl-D-alanine, -S-benzyl-D-cysteine, -D-leucine
