Abstract

In this account, we describe a useful synthetic approach to construct diverse constrained α,α-dialkylated amino acid derivatives using ethyl isocyanoacetate as a glycine equivalent. Various unusual amino acid derivatives, such as cyclophane-, benzocyclo­butene-, and diene-containing systems, are reported here.
