therapeutics 2 as well as fungicides and herbicides. 3 They have also been used widely for the sequence analy- sis of polypeptides and proteins (Edman degradation). 4 These compounds are usually prepared by reaction of aminoacids or aminoacidesters with an isothiocyanate. 5 A few of the 2-thiohydantoins have been synthesized by reaction of aminoacids with dithiocarbamate esters. 6 We have recently
