Notes:
5-Arylidene-3-phenyl-2,4-thiazolidinediones 1a-h undergo ring cleavage with excess benzylamine to give an equimolar mixture of phenyl benzyl urea 5 and dibenzyl urea 6. The intermediate in this type of reaction is isolated under controlled conditions and proved to be 1,5-dibenzyl-3-phenyl biuret 3. Using hydrazine, each of 1d-g gives the corresponding biuret derivative 7a-d, respectively. The cleavage occurs at 1,2 as well as 4,5 bonds.
