Several new cyclicguanidinoacids have been prepared by the reaction of cyclic isothioureas with aminoacids. The ethyl esters of some of these acids have been converted into dialkylaminoalkylamides by refluxing with dialkylaminoalkylamines in the presence of an inert solvent. A series of dialkylaminoethyl esters of the 2-(carboxyalkylamino)-2-imidazolines also have been prepared.
