Thiazole, 2-phenyl or-alkyl substituted one and benzothiazole are efficiently arylated with
aryl bromides at the 2-and/or 5-position (s) in the presence of Pd (OAc) 2 and a bulky …

A modular and practical synthesis of highly substituted oxazoles has been developed. The
transformation consists of a sequential copper-catalyzed amidation of vinyl halides followed …

The fragmentation of N-acyl-isoxazol-5-ones using visible light photoredox catalysis has
been disclosed. The catalyst-controlled divergent mechanisms, namely the oxidative and …

A highly efficient palladium-catalyzed arylation of azoles at the C2-position using 1-
aryltriazenes as aryl reagents was developed. Azoles including oxazoles, thiazoles …

Abstract Directly linked 1, 3-azoles are found as substructures in important naturally
occurring products that have interesting biological activities as well as fascinating structures …

The direct carbonylation of C− H bonds in the benzene ring of N-phenylpyrazoles via
catalysis by ruthenium or rhodium complexes is described. The reaction of N …

Lithiated alkoxyallenes, nitriles, and carboxylic acids have been employed as precursors in
a three‐component reaction leading to highly substituted β‐alkoxy‐β‐ketoenamides. Upon …

4-Bis (methylthio) methylene-2-phenyloxazol-5-one has been shown to be a versatile
template for the synthesis of various 2-phenyl-3, 4-substituted oxazoles via nucleophilic ring …

The severe acute respiratory syndrome (SARS) virus depends on a chymotrypsin-like
cysteine proteinase (3CLpro) to process the translated polyproteins to functional viral …

Direct exposure of human skin to sunlight leads to suppression of the immune system,
believed to be mediated by urocanic acid. The synthesis of oxazole and thiazole analogues …
