M. Marinozzi et al., SYNTHESIS OF 6,6-DICARBOXY-3,4-METHANO-L-PROLINE, A NEW CONSTRAINED GLUTAMATE ANALOG ENDOWED WITH NEUROPROTECTIVE PROPERTIES, Il Farmaco, 51(2), 1996, pp. 121-124
6,6-Dicarboxy-3,4-methano-L-proline (L-DCMP, 7) has been prepared by t
he rhodium(II)acetate dimer catalyzed decomposition of dimethyl diazom
alonate in the presence of a 3,4-didehydroproline derivative. When eva
luated against NMDA- and kainate-induced toxicity in cultured cortical
neurons, L-DCMP (7) exhibited good neuroprotective activity.
