Lithium mesylate organic
WebMesylate, as leaving group There are very many enantiomerically pure starting materials available cheaply from nature. The amino acids are varied in structure and the hydroxy acids such as malic acid 11 and lactic acid 13 provide another resource. We shall give just one example of this kind of synthesis. Ethyl lactate 14 can be converted into the mesylate (a … WebTherefore, leaving groups that form resonance structures upon leaving are considered to be excellent leaving groups. The following diagram shows sulfur derivatives of the type ROSO 3- and RSO 3-. Alkyl sulfates and sulfonates like the ones shown make excellent leaving groups. This is due to the formation of a resonance stabilized structure upon ...
