Abstract
A palladium-catalyzed cross-coupling of 3-iodoazetidines and nonheteroaryl boronic acids was reported. The [1,1'-biphenyl]-2-yldicyclohexylphosphane ligand enabled the reaction that favored the formation of 2-aryl azetidines. The control experiments indicated that the reaction can proceed through either a palladium-hydride/dihydroazete complex or free dihydroazete intermediate followed by hydropalladation.

Abstract
The present study reports, for the first time, the synthesis and structural features of azetidine-borane complexes, as well as their reactivity in lithiation reactions. A temperature-dependent stereoselectivity has been disclosed in the reaction of borane with N-alkyl-2-arylazetidines, allowing for a stereoselective preparation of azetidine-borane complexes 2 and 3. A regioselective hydrogen/lithium permutation, at the benzylic position, was observed in lithiation reactions of complexes possessing a syn relationship, between the ring proton and the BH3 group. In contrast, scarce or no reactivity was noticed in complexes lacking such a stereochemical requirement. The configurational stability of the lithiated intermediates has also been investigated, in order to shed some light on the stereoselectivity of the lithiation/electrophile trapping sequence. Calculations helped in supporting experimental observations, concerning structure and reactivity of these azetidine-borane complexes. Data suggest that the BH3 group could promote the lithiation reaction likely by an electrostatic complex induced proximity effect. Interestingly, a new synthetic strategy for the synthesis of N-alkyl-2,2-disubstituted azetidines has been developed.

Abstract
A strain-release-driven, cation-templated intramolecular nucleophilic addition of tethered alkoxides to prochiral cyclopropenes is described. Employment of chiral β- and γ-amino alkoxides allowed for highly diastereoselective assembly of a small series of enantiopure cyclopropane-fused oxazepanones. It was shown that the chiral center at C-4 plays a crucial role in controlling desymmetrization of the cyclopropenyl moiety, instigated by a profound potassium-templated effect. The preliminary biological activities of the new cyclopropane-fused medium heterocycles against Gram-positive bacteria, Gram-negative bacteria, mycobacteria, cancer cells, and fungus were evaluated.

Abstract
AbstractInterest in molecular structures bearing four-membered heterocycles (FMHs) is growing due to the possibility to explore new regions of the chemical space and get new lead molecules. Our interest in the development of divergent synthesis of functionalized FMHs, prompted us to disclose factors affecting the reactivity of nitrogen-bearing FMHs towards metalating agents. Our investigations demonstrated that structural factors and conformational preferences need to be considered in planning a site-selective functionalization of azetidines. It will be showed how such factors could have pivotal importance in the reactivity of FMHs.

Abstract
A computational study at the MP2(Full)/6-311++G(d,p)//MP2(Full)/6-31+G(d) level of the ammonolysis of halogen substituted azetidines, oxetanes and thietanes was performed in the gas phase and in the commonly used solvent, acetonitrile. Using the free energy of activation of a benchmark reaction for evaluation of synthetic viability, several haloazetidines and oxetanes that possessed the required reactivity were identified; however, no substituted thietane investigated herein was determined to be synthetically useful under the mild conditions selected for this study. In the case of the azetidines, the side reaction of displacement of halide ion was determined to be the preferred reaction course in acetonitrile; however, the amino product of the reactions of the 2-haloazetidines cleaved at an acceptable rate under mild conditions. For the oxetane derivatives investigated, 2-fluorooxetane proved to be a direct source of ring cleavage product. Nucleophilic cleavage of halogen-substituted azetidines and oxetanes is predicted to be a viable source of functionalized three-carbon moieties under mild conditions in organic synthesis.

Abstract
The four stereoisomers of azetidine-2,3-dicaroxylic acid (L-trans-ADC, L-cis-ADC, D-trans-ADC, and D-cis-ADC) were synthesized in a stereocontrolled fashion following two distinct strategies: one providing the two cis-ADC enantiomers and one giving access to the two trans-ADC enantiomers. The four azetidinic amino acids were characterized in a radioligand binding assay ([(3)H]CGP39653) at native NMDA receptors: L-trans-ADC showed the highest affinity (K(i)=10 microM) followed by the D-cis-ADC stereoisomer (21 microM). In contrast, the two analogues L-cis-ADC and D-trans-ADC were low-affinity ligands (>100 and 90 microM, respectively). Electrophysiological characterization of the ADC compounds at the four NMDA receptor subtypes NR1/NR2A, NR1/NR2B, NR1/NR2C, and NR1/NR2D expressed in Xenopus oocytes showed that L-trans-ADC displayed the highest agonist potency at NR1/NR2D (EC(50)=50 microM), which was 9.4-, 3.4-, and 1.9-fold higher than the respective potencies at NR1/NR2A-C. D-cis-ADC was shown to be a partial agonist at NR1/NR2C and NR1/NR2D with medium-range micromolar potencies (EC(50)=720 and 230 microM, respectively). A subsequent in silico ligand-protein docking study suggested an unusual binding mode for these amino acids in the agonist binding site.

Abstract
In the mammalian central nervous system (CNS), the action of sodium dependent excitatory amino acid transporters (EAATs) is responsible for termination of glutamatergic neurotransmission by reuptake of ( S) -glutamate (Glu) from the synaptic cleft. Five EAAT subtypes have been identified, of which EAAT1-4 are present in the CNS, while EAAT5 is localized exclusively in the retina. In this study, we have used an enantioselective chemo-enzymatic strategy to synthesize 10 new Glu analogues 2a- k ( 2d is exempt) with different functionalities in the 4 R-position and characterized their pharmacological properties at the human EAAT1-3. In particular, one compound, 2k, displayed a significant preference as inhibitor of the EAAT2 subtype over EAAT1,3. The compound also displayed very low affinities toward ionotropic and metabotropic Glu receptors, making it the most selective EAAT2 inhibitor described so far.

Abstract
A short and facile approach to biologically interesting N-protected alkyl 3-aminoazetidine-2-carboxylic esters, a new class of conformationally restricted beta-amino esters, was developed. Reduction of anti-beta,gamma-aziridino-alpha-(N-diphenylmethylidene)amino esters and subsequent regioselective intramolecular ring opening of the beta,gamma-aziridine ring via nucleophilic attack of the alpha-amino function afforded the trans-azetidines.

Abstract
Despite the specific importance of four-membered heterocycles with a carbon-heteroatom double bond at the 3-position in organic and medicinal chemistry, little attention has been given up to now to theoretical computational studies on these molecules. However, the overall geometry, and degree of ring puckering especially, could significantly influence the reactivity and biological properties of these four-membered ring compounds. In this paper, focus is made on the influence of different substituents on the equilibrium geometry, ring puckering potential, and thermodynamic quantities. It was found that these properties are mainly affected by the heteroatom (oxygen, nitrogen, sulfur, phosphorus) contained in the ring skeleton. Moreover, the correct description of the puckering potential with the hindered rotor treatment leads to substantial corrections on the thermodynamic properties in the harmonic oscillator approximation.

Abstract
The four stereoisomers of l-2-(2-carboxycyclobutyl)glycine, l-CBG-I, l-CBG-II, l-CBG-III, and l-CBG-IV, were synthesized in good yield and high enantiomeric excess, from the corresponding cis and trans-2-oxalylcyclobutanecarboxylic acids 5 and 6 using the enzymes aspartate aminotransferase (AAT) and branched chain aminotransferase (BCAT) from Escherichia coli. The four stereoisomeric compounds were evaluated as potential ligands for the human excitatory amino acid transporters, subtypes 1, 2, and 3 (EAAT1, EAAT2, and EAAT3) in the FLIPR membrane potential assay. While the one trans-stereoisomer, l-CBG-I, displayed weak substrate activity at all three transporters, EAAT1-3, we found a particular pharmacological profile for the other trans-stereoisomer, l-CBG-II, which displayed EAAT1 substrate activity and inhibitory activity at EAAT2 and EAAT3. Whereas l-CBG-III was found to be a weak inhibitor at all three EAAT subtypes, the other cis-stereoisomer l-CBG-IV was a moderately potent inhibitor with 20-30-fold preference for EAAT2/3 over EAAT1.

Abstract
The natural product kainic acid is used as template for the rational design of a novel conformationally restricted (S)-glutamic acid (Glu) analogue, (1R,4S,5R,6S)-3-azabicyclo[3.3.0]octane-4,6-dicarboxylic acid (1a). The target structure 1a was synthesized from commercially available (S)-pyroglutaminol, in an enantioselective fashion, in 14 steps. Pharmacological characterization of 1a at human glutamate transporter subtypes 1, 2, and 3 yielded K(i) values of 127, 52, and 46 microM, respectively. Furthermore, binding studies at native ionotropic Glu (iGlu) receptors revealed low affinity for alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA)-preferring iGlu receptors (IC(50) > 100 microM), whereas affinities for the KAIN-preferring iGlu receptors and the N-methyl-d-aspartate (NMDA)-preferring group of iGlu receptors were in the low micromolar range (IC(50) = 14 and 2.9 microM, respectively). At metabotropic Glu receptors (mGluR), EC(50) values for 1a were >1000 microM for mGluR1 and 4, representing group I and III, respectively, and approximately 1000 microM (agonist) for mGluR2, representing group II.
