詳細

詳細

N, N-Dimethylformamide dimethyl acetal (DMF-DMA) plays an important role in organic synthesis due to its higher reactivity.

• As a methylating agent, DMF-DMA has been used in the synthesis of methyl esters from acids, methyl ethers, and thioethers from phenols and aromatic thiols.
• DMF-DMA has been used as a formulating agent to synthesize enamines from active methylenes and active methyl groups, and amidines from amines and amides or thioamide.
• It is also possible to produce heterocyclic compounds using DMF-DMA by cyclizing two functional groups.

アプリケーション

N,N-Dimethylformamide dimethyl acetal is used:

• In the synthesis of spirooxindole and pyrazole scaffolds via [3+2] cycloaddition reaction of electron-deficient olefins-based pyrazole motif.
• As a reagent in the synthesis of3-acetyl-4-arylquinoline-based enaminones under microwave irradiation.
