The synthesis is described of analogues of L-tryptophyl-L-methionyl-L-aspartyl-L-phenylalanine amide (the C-terminal sequence of the gastrins) or its N-benzyloxycarbonyl, -t-butoxycarbonyl, or -carbamoyl derivatives wherein the phenylalanyl residue has undergone replacement by other naturally occuring amino-acyl residues or by αα-disubstituted amino-acyl residues, or has been modified by (a) substitution
