NMR-Based Structural Analysis of Highly Substituted Pyridines From Kondrat'eva Aza-Diels-Alder Cycloadditions. [PDF]

Magn Reson Chem
We report the results from a kinetic and mechanistic investigation of an inverse‐electron‐demand Diels–Alder (IEDDA) cycloaddition involving an oxazole‐type diene synthesized via an Ugi–Zhu multicomponent reaction (UZ‐3CR). ABSTRACT Pyridines are a crucial class of heterocycles with widespread applications in natural products, pharmaceuticals, and ...

Core spectroscopy of oxazole

The Journal of Chemical Physics, 2022
We have measured, analyzed, and simulated the ground state valence photoelectron spectrum, x-ray absorption (XA) spectrum, x-ray photoelectron (XP) spectrum as well as normal and resonant Auger–Meitner electron (AE) spectrum of oxazole at the carbon, oxygen, and nitrogen K-edge in order to understand its electronic structure.

Naturally Occurring Oxazole-Containing Peptides [PDF]

Marine Drugs, 2020
Oxazole-containing peptides are mostly of marine origin and they form an intriguing family with a broad range of biological activities. Here we classify these peptides on the basis of their chemical structure and discuss a number of representatives of each class that reflect the extraordinary potential of this family as a source of new drugs.

Microhydration Structures of Protonated Oxazole [PDF]

The Journal of Physical Chemistry A, 2019
The initial microhydration structures of the protonated pharmaceutical building block oxazole (Ox), H+Ox-Wn≤4, are determined by infrared photodissociation (IRPD) spectroscopy combined with quantum chemical dispersion-corrected density functional theory calculations (B3LYP-D3/aug-cc-pVTZ).
