“…At higher pH values, enantioselectivity would be expected to diminish as the dianionic form is populated. Other reports in the literature also assert the importance of pH on enantioselective solution phase separations [27][28][29]. With regard to mass spectrometry, these findings may prompt further evaluation of previous work using antimony(III)-tartrates in ESI-based enantioselective association experiments [14,15] [30], but to our knowledge, this is the first report of such behavior for small molecule enantioselective binding systems, recorded in both solution-phase targeting ESI-MS and gas-phase MS/MS dissociation experiments.…”

“…Am Stickstoffatom von Aminen ist sie gewöhnlich sehr niedrig, so daß stereogene Zentren an dreifach koordinierten Stickstoffatomen nur dann konfigurationsstabil sind, wenn sie wie in Ceftioxid (siehe S. 27), Chinin (siehe S. 38), Dolasetron (siehe S. 78) oder in der Trögerschen Base in ein gespanntes System eingebaut sind, bei dem eine Inversion ohne Bindungsspaltung nicht mehr möglich ist [17].
