Abstract α-Boryl-α-hydrazinoacetic acid is a highly functionalized boron-containing building block that can be easily accessed from readily available α-borylacetaldehyde. The hydrazine motif converted into variety of α-borylated azoles and diazines in straightforward protocol. Furthermore, the carboxy group derivatized to afford novel organoboron compounds should find applications various cross...

Abstract An efficient intermolecular C−H aminohalogenation of indoles with azoles and NXS (X = F, Cl, Br, I) has been developed. This mild protocol provides a straightforward entry to structurally valuable 2‐azolyl‐3‐halogenated in one single operation. In addition, this attractive route for the synthesis polyfunctionalized is great significance due product's versatile reactivity further transf...
