α-Thioureidoalkylation of functionally substituted ureas: II. Synthesis of thio analogs of N-hydroxyalkyl-1,5-diphenylglycolurils
摘要:
Reactions of N-(hydroxyalkyl)ureas with 4,5-dihydroxy-4,5-diphenylimidazolidine-2-thiones gave previously unknown 4,6-dialkyl-1-hydroxyalkyl-3a,6a-diphenyl-5-thioxooctahydroimidazo[4,5-d]imidazol-2-ones which may be regarded as thio analogs of N-(hydroxyalkyl)glycolurils.
