The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2,5-Diphenyloxazole(SMILESS: C1(C2=CC=CC=C2)=NC=C(C3=CC=CC=C3)O1,cas:92-71-7) is researched.Category: pyridazine. The article 《Pd/Cu-Catalyzed C-H/C-H cross coupling of (hetero)arenes with azoles through arylsulfonium intermediates》 in relation to this compound, is published in Organic Letters. Let’s take a look at the latest research on this compound (cas:92-71-7).
A highly efficient method for the selective formal C-H/C-H cross-coupling of 1,3-benzoxazole and (hetero)arenes was established through arylsulfonium intermediates under transition-metal catalysis, which produced a variety of 2-(hetero)aryl azoles RR1 [R = 4-MeC6H4, 4-MeOC6H4, 6-methoxy-3-pyridyl, etc.; R1 = 1,3-benzoxazol-2-yl] in good to excellent yields. Advantages of the reaction included mildness, a good functional group tolerance, a wide range of substrates, a high regio- and chemoselectivity, one-pot procedures and the late-stage functionalization of complex mols. without the use of oxidants, offering a promising strategy for the transition-metal-catalyzed C-H arylation of azoles.
