Total Synthesis of Kalimantacin A.
TLDR
The first total synthesis of kalimantacin A is reported, in which three fragments are prepared and then united via Sonogashira and amide couplings, unlocking routes to further kalIMantacins and analogues for structure-activity relationship studies and clinical evaluation.
