2,2,5-Trimethyl-1,3-dioxane-4,6-dione Usage And Synthesis

Chemical Properties

White to slightly pink crystalline powder

Uses

2,2,5-Trimethyl-1,3-dioxane-4,6-dione is used as a reagent in the synthesis of 3'',4''-bis-difluoromethoxycinnamoylanthranilate (FT061) which is an orally-active antifibrotic agent that reduces albuminuria in rat models of progressive diabetic nephropathy.

Uses

2,2,5-Trimethyl-1,3-dioxane-4,6-dione was used for trapping the adduct formed during the reaction between alkyl isocyanides and dialkyl acetylenedicarboxylates.

General Description

X-ray irradiated single crystals of 2,2,5-trimethyl-1,3-dioxane-4,6-dione have been investigated by electron spin resonance (ESR), electron nuclear double resonance (ENDOR) and electron-electron double resonance (ELDOR) spectra.
