Reaction of 1-aryl-3-(4,4-diethoxybutyl)ureas with phenols. Synthesis of 2-arylpyrrolidines
摘要:
Acid-catalyzed reaction of phenols with 1-(4,4-diethoxybutyl)urea derivatives gave new 2-arylpyrrolidines containing 4-bromoresorcinol and hydroquinone fragments. The described reaction is advantageous due to its mild conditions and no necessity of using expensive or toxic catalyst.
