1,2‐Diazetidines − Structure, Synthesis, and Functionalization
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...

ABSTRACT In this study, ten novel compounds (IPH1–IPH10) were designed by integrating three pharmacophores (isatin, piperazine, and hydrazone) commonly found in the molecular structures of anticancer agents. The target molecules were obtained by the reaction of in‐house prepared 4‐(4‐(pyridin/pyrimidin‐2‐yl)piperazin‐1‐yl)benzohydrazide with various ...

Singlet oxygen-mediated one-pot chemoselective peptide–peptide ligation [PDF]
We here describe a furan oxidation based site-specific chemical ligation approach using unprotected peptide segments. This approach involves two steps: after photooxidation of a furan-containing peptide, ligation is achieved by reaction of the unmasked ...

We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
