Bicyclo[1.1.0]butanes undergo a Lewis acid‐catalyzed formal (3 + 3) annulation with indolyl alcohols to furnish indole‐fused aza‐bicyclo[3.1.1]heptanes. Strain‐release‐driven C‐C bond formation, followed by C‐N bond formation via ring expansion, enables the rapid assembly of rigid, sp3‐rich bicyclic architectures under mild reaction conditions ...

Binding Constants of Substituted Benzoic Acids with Bovine Serum Albumin
Experimental data on the affinity of various substances to albumin are essential for the development of empirical models to predict plasma binding of drug candidates. Binding of 24 substituted benzoic acid anions to bovine serum albumin was studied using

The proton magnetic resonance chemical shifts of N-methyl protons in para-substituted NN-dimethylanilines have been correlated with the Hammett - value of the para substituent. The correlation yields - values of 1.57 0.09 and 0.85 0.09 for the para

Pb NMR, and Hammett Correlations
The synthesis, structure, and spectroscopic details of a series of ß-diketiminato lead(II) alkyl complexes are described. The Hammett correlation between the 207Pb NMR chemical shifts and spara Hammett constant was examined computationally and found to ...

Synthesis, IR and NMR spectral correlations in some symmetrical diimines
A series of diimines have been synthesized by coupling of diamine with substituted benzaldehydes. The purities of these diimines were checked by their analytical and spectroscopic data. The spectral frequencies νCN (cm-1), NMR chemical shifts (δ, ppm) of

Click chemistry has evolved from making covalent connections to also breaking bonds. Here, a cascade assembly is reported that combines these maneuvers to build multifunctional biomolecular scaffolds in a modular one‐pot reaction. The unifying azide release‐tetrazine hub clicks with a trans‐cyclooctene tag, rapidly liberates N,N‐dimethylaniline to ...

Relationship between electrophilicity index, Hammett constant and nucleus-independent chemical shift [PDF]
Inter-relationships between the electrophilicity index (Ω), Hammett constant (óp @#@) and nucleusindependent chemical shift (NICS (1) - NICS value one ångstrom above the ring centre) have been investigated for a series of meta- and para-substituted ...
