The general applicability of preparing aminimides from esters and insitu generated 1,1,1-trimethylaminimine is reported. Acyclic, alicyclic, aromatic, and heteroaromatic trimethylaminimides have been synthesized by the one-step reaction. The synthetic scheme consists of reacting an ester with a 1,1,1-trimethylhydrazinium salt in the presence of an anhydrous base such as sodium methoxide. The choice of solvent, reaction temperature, and base and the electronegativity of the acyl substituent influence the ease of aminimide formation.

A new strategy for the synthesis of ketones is presented based upon the decarboxylative coupling of N-hydroxyphthalimide (NHP) esters with S-2-pyridyl thioesters. The reactions are selective for the cross-coupled product because NHP esters act as radical donors and the thioesters act as acyl donors. The reaction conditions are general and mild, with over 40 examples presented, including larger fragments and the 20-mer peptide Exendin(9-39) on solid support.
