Preparation of oxazolines and oxazoles via a PhI(OAc)2-promoted cyclization of N-propargylamides.
Organic and biomolecular chemistry, 2018A metal-free cyclization of N-propargylamides for the synthesis of various oxazolines and oxazoles via a 5-exo-dig process is presented. Using (diacetoxyiodo)benzene (PIDA) as a reaction promoter and lithium iodide (LiI) as an iodine source ...

ChemInform Abstract: REACTIONS OF OXAZOLES. (REVIEW)
Chemischer Informationsdienst, 1976The reactions of oxazoles involving 1, 2- and 1, 4-cycloaddition, aromatic substitution, and nucleophilic addition leading to cleavage of the heterocyclic ring are examined.

The chemistry of oxazoles and oxazolines in foods
C R C Critical Reviews in Food Science and Nutrition, 1981This review attempts to present and discuss the current status of oxazoles and oxazolines relative to foods. Special emphasis is placed on their occurrences in foods, sensory properties, isolation and synthesis techniques, and pathways of formation in foods and related model systems.

The first heterogeneous gold(I)-catalyzed [2 + 2 + 1] annulation of terminal alkynes, nitriles, and oxygen atoms has been achieved by using an MCM-41-immobilized phosphine-gold(I) complex as catalyst and 8-methylquinoline N-oxide as oxidant under mild ...

On the electronic structure of oxazole
Tetrahedron, 1963Abstract The π-electronic properties of oxazole are calculated by the semiempirical self-consistent field-molecular orbital method. The parameters necessary for the computation are taken from previous self-consistent field studies of furan and imidazole.

Pd-Catalyzed Desulfonative Cross-Coupling of Benzylic Sulfone Derivatives with 1,3-Oxazoles.
Organic Letters, 2017The Pd-catalyzed desulfonative cross-coupling reaction of benzylic sulfone derivatives with 1,3-oxazoles via a deprotonative pathway has been developed. Broad substrate scope for both sulfone and 1,3-oxazole partners is observed, affording a variety of 1,

ChemInform Abstract: REACTION OF VINYLPYRIDINES WITH OXAZOLES
Chemischer Informationsdienst, 1980Depending on the structure, the reaction of the hydrochlorides of 2- and 4-vinylpyridines and 2-methyl-5-vinylpyridine with oxazoles leads to the synthesis of dipyridyls with or without a hydroxy group. It is shown that the regiospecificity of the reaction can be predicted on the basis of quantum-chemical calculations with the aid of the concepts of MO
