General description

1,2-Dimethoxyethane (DME) is an inert aprotic polar solvent for electrolytes of lithium batteries, polysilicones, oligo- and polysaccharides.

Application

1,2-Dimethoxyethane can be used as a solvent to synthesize:
  • Oxazoles from α-acylamino ketones via Robinson-Gabriel reaction.
  • 5-Arylhistidines via Suzuki-Miyaura cross-coupling between 5-bromohistidine and arylboronic acids.
  • Aryl thioethers via Pd-catalyzed thioetherification of aryl halides with aliphatic and aromatic thiols.

Glymes (i.e. glycol diethers) were explored as alternative benign solvents for enzymatic reactions, specifically the lipase-catalyzed transesterification. Long-chain glymes were found highly compatible with immobilized Candida antarctica lipase B (iCALB), leading to higher enzyme activities and stabilities than t-butanol and
