Enantiosclective Synthesis of Pyrroloindolines and Tryptophan Derivatives by an Asvmmetric Protonation Reaction
<p>Pyrroloindoline and unnatural tryptophan motifs are important targets for synthesis based on their incorporation into a diverse array of biologically active natural products. Both types of alkaloids have also found applications as chiral catalysts and tryptophan derivatives are commonly emp...
