importance of enzyme mimics in organic synthesis inspired us to design a novel biomimetic synthesis of β-carboline alkaloids directly from tryptophan and a second amino acid. This novel one-pot protocol utilizes abundant and readily available starting materials and thus presents a green and user-friendly alternative to conventional methods that rely on stepwise synthesis. Driven by molecular iodine and TFA

A three-step redox-economical synthesis of α-substituted α-N-phthaloyl aldehydes was developed using Fukuyama reduction from commercially available amino acids. The developed method provided various α-substituted α-N-phthaloyl aldehydes (16 entries) in 29–98 % yields. The developed protocol was reproducible on a large scale.
