Abstract
Pyranones are important scaffolds in synthetic and natural product chemistry, with the 2H-pyran-2-one and 4H-pyran-4-one structural motifs commonly found in naturally occurring compounds. A variety of metal-free and metal-catalyzed approaches have been used to construct pyranone architectures. Furthermore, 2H-pyran-2-one ring systems can undergo a range of transformations such as electrophilic reactions, nucleophilic reactions, ring contractions, photochemical reactions, and cycloaddition reactions. This is an update to Section 14.3, and covers the major developments in the synthesis and reactions of pyranones and pyranthiones achieved since 2003.
