PhD (Harvard) Establishing new principles of organic synthesis: Green Reaction Discovery, Protein Conjugation, Bio-inspired total synthesis of natural products

[Teck-Peng LOH Research Group @lab_TPLoh]

We introduce a new disulfide bond metathesis strategy using Koser's reagent as a radical initiator, enabling biocompatible, bidirectional reactions under mild conditions, with potential in drug development, protein engineering, and biomedical applications.

We present an amine-differentiating amide synthesis using an sp-carbon-activated ester. The bulky TIPS group prevents unwanted reactions while allowing for easy removal, facilitating post-modifications like click reactions and peptide-drug conjugations.

Inspired by nature, we used water as both solvent and reagent in developing a metal-free deuteration catalyzed by triaryl carbenium ion-pair. This approach offers a sustainable alternative to traditional H/D exchange, addressing metal-related challenges.

Our new metal-free approach enables 1,3-addition of amines to α,β-unsaturated aldehydes without directing groups. By using iodine and an oxidant, it yields unsaturated α-amino acetals, crucial for synthesizing bioactive molecules and pharmaceuticals.
