2. ChemInform Abstract: Regiodivergent Heterocyclization: A Strategy for the Synthesis of Substituted Pyrroles and Furans Using α-Formyl Ketene Dithioacetals as Common Precursors.

Author

Wu, Ting, Pan, Ling, Xu, Xianxiu, and Liu, Qun

Subjects
*HETEROCYCLIC chemistry, *PYRROLES, *CHEMICAL synthesis, *FURANS synthesis, *ALDEHYDES, *CHEMICAL precursors, *CHEMICAL reactions
Abstract

The reaction of dithioacetals (I) with nitriles (II) followed by a zinc-mediated one-pot reaction of the isolable intermediate (V) leads to 5-ethylthiopyrroles (III), whilst the copper-mediated reaction of the intermediate (V) affords 4-ethylthiocarbonylpyrroles (IV) via a second isolable intermediate (VI).

Author

Zhang, Xue, Feng, Chengjie, Jiang, Tao, Li, Yifei, Pan, Ling, and Xu, Xianxiu

Subjects
*PYRROLE derivatives, *ORGANIC synthesis, *REGIOSELECTIVITY (Chemistry)
Abstract

The regioselective one-pot [3 + 2]-cycloaddition/iodocyclization cascade reaction of alkyne-tethered cinnamates/chalcones and toluenesulfonylmethyl isocyanide (TosMIC) shows a dedicated solvent dependence. [ABSTRACT FROM AUTHOR]
