Palladium-Catalyzed Intermolecular Oxidative Coupling Reactions of (<i>Z</i>)-Enamines with Isocyanides through Selective β-C(sp<sup>2</sup>)-H and/or C=C Bond Cleavage
two efficient palladium‐catalyzed intermolecular oxidative couplingreactions of (Z)‐enamines with isocyanides via selective β‐C(sp2)‐H and/or C=C bond cleavage have been developed, leading to controllable chemodivergent and stereoselective construction of a wide range of (E)‐β‐carbamoylenamine derivatives containing strong intramolecular hydrogen bonds. Furthermore, possible reaction pathways for these

The reaction of methyl 3-(arylamino)acrylates with hydrogen iodide gave 1,2-dihydroquinoline-3-carboxylic acid derivatives at room temperature. This reaction proceeds efficiently in alcoholic solvent; bulky tert-butyl alcohol is the best solvent to give the 1,2-dihydroquinoline derivatives. It is particularly interesting that hydrogen iodide is the most efficient acid to achieve this reaction in tert-butyl
