We report herein an efficient, stereocontrolled, and chromatography-free synthesis of the novel broad spectrum antibiotic GDC-5338. The route features the construction of a functionalized tripeptide backbone, a high-yielding macrocyclization via a Pd-catalyzed Suzuki-Miyaura reaction, and the late-stage elaboration of key amide bonds with minimal stereochemical erosion. Through extensive reaction development and analytical understanding, these key advancements allowed the preparation of GDC-5338 in 17 steps, 15% overall yield, >99 A % HPLC, and >99:1 dr.

The first total synthesis of mycocyclosin, a diketopiperazine natural product isolated from M. tuberculosis, is described. While direct oxidative coupling of tyrosine phenolic groups was unsuccessful, construction of the highly strained bicyclic framework was successfully accomplished through an intramolecular Miyaura-Suzuki cross-coupling to generate the biaryl linkage.
