The first enantioselective catalytic total synthesis of (–)-pyridovericin is reported. The key steps involve a modified HWE reaction under aqueous conditions and an asymmetric iridium-catalyzed hydrogenation. This resulted in a highly modular and stereoselective approach that delivered the target natural product in high yield and stereoselectivity.
