The copper-catalyzed multicomponentreaction of 2-iodobenzamides, NaN3 and terminal alkynes for the synthesis of 2-(1,2,3,-triazolyl)benzamide derivatives was achieved in a one-step process and short period of time under mild reaction condition. The transformations consisted of C(aryl)-N bond formation and azide-alkyne cycloadditon. The absence of an external base was found to be crucial in determining
Different Lewisacid promotor-steered highly regioselective phosphorylation of tertiary enamides with diverse H-phosphonates or H-phosphine oxides was developed. Under the catalysis of iron salt, the phosphonyl group was introduced into the α-position of tertiary enamides, affording various α-phosphorylated amides in high efficiency. On the other hand, the β-phosphorylated tertiary enamides were efficiently

Two is better than one: In the presence of Pd(OAc)2 and Cu(OAc)2, o‐(1‐alkynyl)benzamides 1 were converted into bis‐iminobenzoisofurans with an axiallychiral 1,3‐diene 2 unit. The coexistence of both Pd and Cu catalysts was found to be essential for both the cyclizativedimerization process and for the observed unusual cyclization mode.
