The ability to differentiate and selectively activate remote C–H bonds represents a perennial challenge in the field of C–H activation. Since its first report in 2012, a now-established “directing template” (DT) approach remains demonstrably

Highly enantioselective Darzens-type epoxidation of diazoesters with glyoxal derivatives was accomplished using a chiral boron-Lewis acid catalyst, which facilitated asymmetric synthesis of trisubstituted α,β-epoxy esters. In the presence of a chir
