An abstract of the article "Molecular Iodine Mediated Oxidative Cross-Coupling of sp³ C-H with sp² C-H: Direct Synthesis of Substituted Indolo[2,3-b]carbazoles via Formal [2 + 2 + 1 + 1] Cyclization" by W.-J. Xue and colleagues is presented.

The article presents chemical equations related to the article "Iodine-Promoted Selective Synthesis of Substituted Aminothiazole via a Self-Sorting Reaction Network" by W.-J. Xue and others, published in the "Tetrahedron Letters" in 2014.

A new method to synthesize indole-2,3-diones and 2-hydroxy-3(2H)-benzofuranones is developed via a one-stop oxidative cyclization of the corresponding ortho-functionalized acetophenones (I) and (III). [ABSTRACT FROM AUTHOR]

A mechanism for the synthesis of polysubstituted oxazole derivatives (III) from methyl ketones (II), benzoin (I) and ammonium acetate is suggested. [ABSTRACT FROM AUTHOR]
