hindered, oxidation‐sensitive and chiral amines. Examples for the synthesis of both acyclic and cyclic guanidines are provided. 2‐Propoxyphenyl iodide (2‐PrOPhI) by‐product, generated from the oxidant [N‐(p‐toluenesulfonyl)imino](2‐propoxyphenyl)iodinane (2‐PrOPhINTs), can be isolated in high yields making regeneration of the hypervalent iodine reagent possible. The utility and greenness of the synthetic

The invention relates to a process for the manufacture of a cephalosporin derivative of the formula I: ##STR1## in which X is a sulphur or oxygen atom or a sulphinyl radical, R.sup.1 is any one of the C-3 substituents from antibacterially-active cephalosporins known in the art, R.sup.2 is a hydrogen atom or a 1-6C alkyl or 2-6C alkenyl radical, R.sup.3 is a hydrogen atom or one of a variety of radicals defined in the specification, and the pharmaceutically-acceptable acid- and base-addition salts thereof, characterized by reaction of a compound of the formula IX: ##STR2## in which R.sup.16 and R.sup.17 individually have one of the values given above for R.sup.2 and R.sup.3, or a derivative thereof in which the carbonyl group is masked, with a compound of the formula X: ##STR3## in which R.sup.18 is a hydrogen atom or any one of the cephalosporin 3-carboxylic acid protecting groups known in the art; whereafter, when R.sup.18 is other than a hydrogen atom, the protecting group R.sup.18 is replaced by hydrogen by conventional means.
