  摘要：

  The asymmetric synthesis and biological activity of (2S,1'S,2R,3R)-2-(2 -carboxy-3'-hydroxy-methylcyclopropyl) glycine ((+)-3) is described. This novel C-3' substituted carboxy cyclopropyl glycine is a highly potent group 2 and group 3 mGluR agonist that has proven to be orally active in both fear potentiated startle (animal model for anxiety) and PCP-induced motor activation (animal model for psychosis) assays in rats.

• Synthesis of 3,5-diazabicyclo [5.1.0] octenes. A new platform to mimic glycosidase transition states

  All-cis 1-hydroxymethyl 2,3 bis-aminomethyl cyclopropane was used to construct the first 3,5-diazabicyclo [5.1.0]-3-octenes. This system has the interesting ability to exist in a conformation that resembles a snapshot of a glycoside hydrolysis reaction with respect to charge and geometric analogy to an oxocarbenium ion, and the positioning of the departing aglycon. The cis-configured cyclopropane core was synthesized by Cu-catalyzed intramolecular cyclopropanation of benzyl protected cis-2-butene-1.4-diol diazoacetate ester. Serial functionalization to bis-aminomethyl cyclopropanes and subsequent cyclization to amidines lead to the target bicyclic compounds in good overall yields. Several glycosidases were surveyed for the inhibitory potential of these transition state analogs, and amongst them, selective competitive inhibitors with micromolar K(i) values were identified.
