The somatostatin receptor subtype 2 (SSTR2) is often highly expressed on neuroendocrine tumors (NETs), making it a popular in vivo target for diagnostic and therapeutic approaches aimed toward management of NETs. In this work, an antagonist peptide (ssts
Silver-Catalyzed Cascade Cyclization/1,6-Conjugate Addition of Homopropargyl Sulfonamides to p-Quinone Methides: An Approach to Diverse 3-Diarylmethine Substituted Dihydropyrroles

A silver-catalyzed cycloisomerization/1,6-conjugate addition of homopropargyl sulfonamides to p-quinone methides to access diverse diarylmethine substituted dihydropyrroles has been disclosed. The reaction pathway involves an intramolecular cascade cyclization of homopropargyl sulfonamides to generate a highly reactive dihydropyrrole intermediate in situ followed by conjugate addition with p-quinone methides. This method provides an efficient and scalable route for the synthesis of 3-diarylmethine substituted dihydropyrroles, in one pot.
New polyelectrolytes based on 4-vinyl-1,2,3-triazole and 1-vinylimidazole

Copolymers of 4-vinyl-1,2,3-triazole and 1-vinylimidazole (VI) were obtained by radical copolymerization of (4-vinyl-1H-1,2,3-triazol-1-yl)methyl pivalate with VI followed by alkali hydrolysis. Reactivity ratios of the triazole and imidazole monomers are 0.51 and 0.30, respectively. Theoretical quantum-chemical calculations by the PM3 semiempirical method give close values, which show that the obtained reactivity ratios reflect the activity of the vinyl groups. Polyelectrolyte properties of the copolymers were studied by potentiometric titration. Hydrogen bonds between the protonated triazole cycle and the triazole or imidazole units were found to considerably influence the solubility and solution properties of the copolymers.

Using facile, highly modular synthetic approaches, a new monomer family based on a 1,2,3-triazole-4-vinyl building block has been prepared, and various functional derivatives have been obtained. Subsequent homo- and copolymerization of these novel functionalized monomers gives polymeric materials with unique physical properties, combining many attractive features of more traditional monomers, such as styrene, vinylpyridine, and meth/acrylates.

Cross-couplings between amides and 1,2-dihaloalkenes are an efficient and straightforward way to access β-haloenamides which, in turn, can be functionalized into complex, stereodefined enamide motifs. However, the intramolecular version of these cross-couplings, leading to cyclic β-haloenamides, has not been formally studied. In this paper, we report an investigation of factors affecting the efficiency of the reaction and its selectivity between potential exo and endo cyclization products. We demonstrate that exo/endo selectivity is largely determined by ring strain, whether it arises from the size of the resulting ring or from the structure of the starting compound, but that selectivity can also be modulated by varying reaction conditions. Finally, we show that resulting β-haloenamides readily undergo transition metal-catalyzed reactions, making this sequence a viable way to access highly functionalized cyclic enamides.

A technically simple approach for rapid, high-yielding and site-selective bioconjugation has been developed for both in vitro and cellular applications. This method involves the generation of maleimido-phosphonium ylides via 4-nitrophenol catalysis under physiological conditions followed by their Wittig reactions with aldehyde-appended biomolecules.
