The N-substituted alkyl sulfoximine derivatives are a new chemical family of neonicotinoid insecticides. We have designed and synthesized 10 (1,3-thiazole)alkyl sulfoximine derivatives. All compounds were identified by 1H and 13C nuclear magnetic resonance (NMR), IR, and elemental analyses. Preliminary bioassays indicated that some title compounds exhibited good insecticidal activities at 10 mg/L against Myzus persicae. The relationship between structure and biological activity was also discussed.

ZnS and Cu:ZnS nanoparticles were prepared by aqueous chemical method and characterized by several analytical tools. Nanoparticles have an average size of about ? 18 nm and possess highly open mesopores, moderate surface area, and uniform morphology. UV?vis spectra designate that doping of Cu shifted the optical response of the ZnS nanoparticles in to a visible region. These Cu:ZnS nanoparticles were employed as a photocatalyst for chemoselective synthesis of 2-substituted azoles by the reaction of benzyl bromides and 1,2-Diaminobenzene or 2-Mercaptoaniline in visible light. Analogous experiments confirmed that the reaction were proceeds through one pot C?N arylation/ CSp3? H oxidation/ cyclization/dehydration sequence. The enhanced catalytic activity by doping could be attributed to the presence of trapping level generated by copper doping which augments the relaxation time of electron and holes so that they are easily available for the reaction. The method was also applicable for the synthesis of quinazolin-4(3H)-ones.

Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.

A new organocatalytic strategy for the synthesis of enantioenriched aza-Baylis?Hillman type products via a frustrated vinylogous reaction is presented. This process proceeds under mild conditions with good yields, completed Z/E selectivity and excellent enantioselectivities. Moreover, easy derivatizations of the final products led to important building blocks of organic synthesis such as 1,3-aminoalcohols and Lewis base catalysts.

Single amino acid chelate (SAAC) systems for the incorporation of the M(CO)3 moiety (M = Tc/Re) have been successfully incorporated into novel synthetic strategies for radiopharmaceuticals and evaluated in a variety of biological applications. However, the lipophilicity of the first generation Tc(CO)3-dipyridyl complexes has resulted in substantial hepatobiliary uptake when either examined as lysine derivatives or integrated into biologically active small molecules and peptides. Here we designed, synthesized, and evaluated novel SAAC systems that have been chemically modified to promote overall Tc(CO)3L3 complex hydrophilicity with the intent of enhancing renal clearance. A series of lysine derived SAAC systems containing functionalized polar imidazole rings and/or carboxylic acids were synthesized via reductive alkylation of the epsilon amino group of lysine. The SAAC systems were radiolabeled with 99mTc, purified, and evaluated for radiochemical stability, lipophilicity, and tissue distribution in rats. The log P values of the 99mTc complexes were determined experimentally and ranged from -0.91 to -2.33. The resulting complexes were stable (>90%) for at least 24 h. Tissue distribution in normal rats of the lead 99mTc complexes demonstrated decreased liver (<1 %ID/g) and gastrointestinal clearance (<1.5%ID/g) and increased kidney clearance (>15 %ID/g) at 2 h after injection compared to the dipyridyl lysine complex (DpK). One of the new SAAC ligands, [99mTc]bis-carboxymethylimidazole lysine, was conjugated to the N-terminus of Tyr-3 octreotide and evaluated for localization in nude mice bearing AR42J xenografts to examine tissue distribution, tumor uptake and retention, clearance, and route of excretion for comparison to 111In-DOTA-Tyr-3-octreotide and 99mTc-DpK-Tyr-3- octreotide. 99mTc-bis-(carboxymethylimidazole)-lysine-Tyr-3- octreotide exhibited significantly less liver uptake and gastrointestinal clearance compared to 99mTc-DpK-Tyr-3-octreotide while maintaining tumor uptake in the same mouse model. These novel chelators demonstrate that lipophilicity can be controlled and organ distribution significantly altered, opening up broad application of these novel SAAC systems for radiopharmaceutical design.
