These are described spirolactam derivatives of formulae (Ia) and (Ib) ##STR1## wherein R represents a hydrogen atom or a conventional nitrogen protecting group; R.sup.1 represents a hydrogen atom or a conventional carboxyl protecting group or activating group; R.sup.2 represents the side chain of any naturally occurring amino acid; m represents 1 or 2; n represents 1 or 2; the confirguration at * may be (R) or (S) or a mixture thereof; with the proviso that when R represents the nitrogen protecting group R.sup.3 --CO(O)-- (where R.sup.3 represents (CH.sub.3).sub.3 C--), the group --CO.sub.2 R.sup.1 represents the protected carboxy group --CO.sub.2 CH.sub.3, m is 1 and n is 1 in the compounds of formula (Ib); R.sup.2 may not represent an arylmethyl group; and solvates or acid addition salts thereof. These derivatives are of value in the preparation of spirolactam compounds which, depending on their stereochemistry, are either antagonists or agonists of substance P, and as such have a variety of therapeutic properties.
