Applicazioni

N,N-Dimethylformamide dimethyl acetal (DMF-DMA) can be used as: 
  • An organocatalyst for the synthesis of 1,2-disubstituted-3,4-dihydronaphthalenes by the reaction of vinylarenes and electron-deficient alkynes.       
  • A building block for the preparation of heterocyclic compounds such as enamines and amidines via formylation of methylene and amino groups.       
  • A reagent in the synthesis of 1,4-diaryl-piperazine-2,5-diones by reacting with chloroacetamides.        
  • A reagent along with enamine and alkyne for the preparation of 2,3,4,5-tetrasubstituted pyridine derivatives by three-component coupling reaction in the presence of Me3SiCl.

A novel series of analogues of calcitriol (1) is developed featuring a spirocyclic central core resulting from C18/C21-connection and C15/C16-deletion (2a, 2b). The synthesis of the key intermediate involves an Eschenmoser rearrangement of an enantiomerically pure bromo-substituted cyclohexenol.

1-Methylimidazole exhibits an unusually high efficiency in promoting the reaction of aryl methyl ketones with DMF-DMA to form (2E)-1-aryl-3-dimethylamino-2-propenones which lacks correlation between the catalytic efficiency and the basicity of 1-methylimidazole in comparison to other amines.
