Abstract

Your choice: The choice of the Ru‐pincer‐complex catalyst determines if peptides or pyrazines are formed from β‐amino alcohols. Use of PNN complex 1 leads to linear poly(alanine) or to cyclic dipeptides, depending on the R group (see scheme). With the PNP complex 2, pyrazines are formed. These reactions are homogeneously catalyzed under neutral conditions and are environmentally benign.
