  Enantiospecific Synthesis of Natural (−)-Cocaine and Unnatural (+)-Cocaine from d- and l-Glutamic Acid

  摘要：

  Natural (-)-cocaine and unnatural (+)-cocaine have been synthesized enantiospecifically from D- and L-glutamic acid, respectively. The axial-equatorial substitutents were introduced by a stereo- and regiospecific dipolar cycloaddition to the corresponding (LR,5S)- and (1S,5R)-N-BOC-nortropenes with (ethoxycarbonyl)formonitrile N-oxide. A sequence of subsequent stereochemically controlled transformations converted the fused isoxazoline to the requisite P-hydroxy ester. Synthesis of the key intermediate N-BOC-nortropenes involved construction of the 8-azabicyclo[3.2.1]octane framework by Dieckmann condensation of cis-5-substituted D-and L-proline esters. For comparison, (1R,SS)-N-BOC-nortropene also was derived by degradation from natural cocaine. The cis-5-substituted D-and L-proline esters were obtained by sulfide contraction and subsequent catalytic hydrogenation to induce stereospecifically the C-5 stereochemistry from D-and L-thiopyroglutamate, which in turn were prepared from D-and L-glutamic acids, respectively.

  2 beta-carboxylic acid are highly potent and highly selective for the DA transporter. The isopropyl esters of 3 beta-(4'-chlorophenyl)- and 3 beta-(4'-iodophenyl)tropane-2 beta-carboxylic acid also possess high DA affinity and show significant DA transporter selectivity. Similarly, the phenyl and isopropyl ester analogues of cocaine are much more selective for the DA transporter than cocaine. Tertiary
