Trimethylacetic anhydride is used as acylation and esterification reagents. It is involved in acylation and esterification reactions with anilines and phenols. It is also used in solid-phase oligonucleotide synthesis and in the kinetic resolution of racemic 2-hydroxy-gamma-butyrolactones with diphenylacetic acid. It is also employed in the production of cyano-4, N-tert-butyloxycarbonyl piperidine.
The direct hydrogenation of carboxylic acids to aldehydes has been achieved in the presence of pivalic anhydride and Tetrakis(triphenylphosphine)palladium(0), 10548 : Chem. Lett., 1143 (1998).
Alcohols can be protected as their pivaloyl (Pv) esters by reaction with the anhydride in the presence of MgBr2 - Et3N or Sc(OTf)3 in acetonitrile: J. Org. Chem., 61, 5702 (1996). See also Trimethylacetyl chloride, A15051 .
