Iodine catalyzed synthesis of 2,5-substituted oxazoles from N-arylethylamides through intramolecular C(sp3)–H functionalization under metal-free conditions is described.
construction of a rich chemical space of arylethylamine motif. In this report, a practical protocol for the synthesis of arylethylamine functionality common in pharmaceutical chemicals has been developed. It proceeds by Mn-catalyzed anti-Markovnikov hydroarylation of electron-rich enamides under mild conditions without the use of ligands. In spite of mismatched electronic effects during the manganese-mediated

Organoborane-catalyzed hydroboration of nitriles provides N,N-diborylamines, which act as efficient synthons for the synthesis of primary amines and secondaryamides. Known nitrile hydroboration methods are dominated by metal catalysis. Simple and metal-free hydroboration of nitriles using diborane [H-B-9-BBN]2 as a catalyst and pinacolborane as a turnover reagent is reported. The reaction of monomeric
