Intramolecular hydrogen bonding-assisted cyclocondensation of α-diazoketones with various amines: a strategy for highly efficient Wolff 1,2,3-triazole synthesis
chemistry can be exploited for the synthesis of diverse ranges of small molecules from α-diazo carbonyl compounds. In this paper, three synthetic approaches to α-diazo amides are described, and their scope and limitations are determined. On the basis of these synthetic studies, recommendations are provided to assist the selection of the most appropriate approach for specific classes of product. The
