Elgindy, CecileMalins, Lara R.2025-12-312025-12-312667-1107https://hdl.handle.net/1885/733798020In this issue of Chem Catalysis, Walczak and co-workers introduce a carbastannatrane alanine derivative that facilitates amino acid side-chain functionalizations via C–C, C–S, and C–Se bond formation using Stille cross-coupling reactions. Applications in late-stage peptide modifications and macrocyclizations further exemplify the value of this novel building block.3enPublisher Copyright: © 2021 Elsevier Inc.2021-09-1610.1016/j.checat.2021.06.02085126079376
