Novel Bridged Bicyclic α-Amino Acid Esters and Key Derivatives from Quincorine and Quincoridine
摘要:
Oxidation of Quincorine (QCl) and Quincoridine (QCD) has been investigated, giving bicyclic a-amino acids and dicarboxylic acid derivatives, which are epimerically and also enantiomerically pure. Acidic Cr(VI)-mediated oxidation (Jones oxidation) has been optimized with respect to reaction conduct and work up (addition of ethylenediamine).
