Procedure
By way of example of the huge potentialities given by this synthetic route, the synthesis of the novel compound, α,α',α"-tris(methyl)-1,4,7,10-tetraazacyclododecane--1,4,7,10-tetraacetic acid, is reported in Experimental section: ##STR12## as well as that of α,α',α"-tris[(phenylmethoxy)methyl)-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid ##STR13## which, by catalytic hydrogenation, as described in example 6 of the cited Patent, yields α,α',α"-tris(hydroxymethyl)-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid. ##STR14##
