title: Identification of ethyl pyruvate and dihydrocinchonidine adducts by electrospray ionization mass spectrometry.
abstract: Several ethyl pyruvate and dihydrocinchonidine adducts, formed by non-covalent interactions with alkali cations, have been identified for the first time using electrospray ionization mass and tandem mass spectrometry. This type of adduct may have an important role in asymmetric reactions of pyruvates in the presence of cinchonas.
