Abstract

This invention relates to compounds of the formula: ##STR1## wherein R is an electron withdrawing group; R.sub.1 is H or COZ; PA1 X.sub.1 and X.sub.2 are independently H, lower alkyl, PA1 aryl, aryl lower-alkyl or polystyrene or PA1 R and X.sub.1 taken together with the carbon atoms to which they are attached form a ring containing from 4 to 15 ring carbon atoms and may contain up to 2 heteroatoms, wherein the heteroatoms are O, S, or N; and PA1 Z is an amino acid residue, a peptide residue or a leaving group. The compounds of the present invention are adaptable as blocking or protecting groups for an amine composition useful in peptide synthesis. The present invention is also directed to a method of protecting an amino group of an organic molecule during a reaction which modifies a portion of the molecule other than the protected amino group.
