Nature Communications, Vol 14, Iss 1, Pp 1-9 (2023)
Abstract The cross-dehydrogenative coupling (CDC) reaction is the most direct and efficient method for constructing α-tertiary amino acids (ATAAs), which avoids the pre-activation of C(sp3)-H substrates. However, the use of transition metals and har
