N,N-Dimethylformamide di-tert-butyl acetal, tech. 90%
Chemical Properties
Applications
N,N-Dimethylformamide di-tert-butyl acetal is used as a reagent in the synthesis of (S)-2-(1-tert-butoxycarbonyl-2-{4-[2-(5-methyl-2-phenyloxazol-4-yl)ethoxy]phenyl}ethylamino)benzoic acid methyl ester, 3-O-tert-butylmorphine, tert-butylesters of pyrrole and indolecarboxylic acids. Further, it is used in the preparation of indolizines by intermolecular cyclization of picolinium salts.
Notes
Literature References
The conversion of carboxylic acids to their esters using DMF acetals (see for example, N,N-Dimethylformamide dimethyl acetal, A15350 ) can be extended to the preparation of t-butyl esters by using excess reagent in benzene or toluene as solvent: Synthesis, 135 (1983).
