Poly(ethylene glycol)s as grinding additives in the mechanochemical preparation of highly functionalized 3,5-disubstituted hydantoins

Beilstein J. Org. Chem. 2017, 13, 19–25, doi:10.3762/bjoc.13.3

investigated in the presence of various poly(ethylene) glycols (PEGs), as safe grinding assisting agents (liquid-assisted grinding, LAG). A comparative study under dry-grinding conditions was also performed. The results showed that the cyclization reaction was influenced by the amount of the PEG grinding

agents. In general, cleaner reaction profiles were observed in the presence of PEGs, compared to dry-grinding procedures. Keywords: ball-milling; 1,1’-carbonyldiimidazole (CDI); hydantoins; mechanochemistry; liquid-assisted grinding (LAG); poly(ethylene) glycols (PEGs); Introduction Poly(ethylene

) glycols (PEGs) are eco-friendly solvents [1][2], finding applications in the biomedical field and for pharmaceutical formulations [3] and catalysis [4]. PEG-based reaction media [1] are safe reaction environments, efficiently heated by microwaves [5], but their use in organic transformations activated by
