Recent Advances for Synthesis of Oxazole Heterocycles via C-H/C-N Bond Functionalization of Benzylamines

摘要

The five membered heteroaromatic oxazole motifs and their scaffolds exhibit significant pharmaceutical and biological applications. Remarkably, the high efficiency in the assembly of structurally diverse oxazole scaffolds via C(sp(3))-H functionalization of benzylamines have attracted synthetic organic chemists. In this review, the different synthetic strategies from benzylamines as a new emerging substrate via C-H/C-N bond functionalization towards oxazole synthesis are discussed in detail. Moreover, it highlights substrate scope along with the reaction mechanism involved during the reaction.
