  4-oxypyridines, and 3-iodo-2,4-oxyquinolines with arylboronic acids are described as a useful and efficient alternative to homogeneous conditions. The methodology features ligand-free and environmentally friendly conditions, and tolerates a wide range of boronic acids. The cross-coupled products can be viewed as useful intermediates for the preparation of 3-aryl-4-hydroxypyridin-2(1H)-ones, which can be used

  A collective synthesis of 4‐hydroxy‐2‐pyridone alkaloids—specifically, pretenellin B, prebassianin B, farinosone A, militarione D, pyridovericin, and torrubiellone C—has been achieved. Key steps include using a strategic convergent method to synthesize the densely substituted pyridone key intermediate by Suzuki–Miyaura cross‐coupling reaction, a divergent synthesis approach of target molecules by aldol
