  Synthesis of Enantiopure 1-Azabicyclo[3.2.2]nonanes via Stereoselective Capture of Chiral Carbocations

  摘要：

  [GRAPHICS]A new class of doubly functionalized and enantiomerically pure 1-azabicyclo[3.2.2]nonanes derived from quincorine and quincoridine is described. 2,5-Disubstituted quinuclidines with a C9-mesyloxy group were easily transformed into the corresponding halides upon treatment with lithium salts. Subsequent silver salt-mediated ring expansion stereoselectively furnished the title azabicyclics. Chiral carbocations which are configurationally stable and nonplanar are postulated to account for the striking stereoselectivity of the capture of external nucleophile. 5-Ethynyl-2-iodomethylquinuclidines afford the alpha-benzoyloxy amines rather than alpha-methoxy amines, even in MeOH.

  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).
