Abstract
Dirhodium(II) tetraacetate catalyzed decomposition of ethyl diazoacetate in the presence of D-Cbz-vinylglycine methyl ester (11) afforded a mixture of the cyclopropyl esters D-CGA A-D(13) from which the corresponding 2R-acids 7-10 were obtained and their absolute configurations assigned. The (2R,3S,4R) α-(carboxycyclopropyl)glycine (D-CGA C, 9 resulted to be the most potent and selective among the NMDAreceptorligands yet reported.File in questo prodotto:
