Synthons 意味

In 1967, E. J. Corey introduced the concept of a synthon in retrosynthetic analysis. Planning the steps of a complex molecule synthesis requires recognizing key synthons and identifying how they can be assembled into a desired product. In many retrosynthetic bond disconnections, the bond is broken heterolytically instead of homolytically, generating a carbocationtic and a carbanionic synthon. Most polar-mechanism reactions, whether they are nucleophilic displacem… WebMar 3, 2024 · Herein is reported the first example of ring opening and skeletal reconstruction of 3-vinyl benzofuranone-chromones 1 as versatile synthons, which can react with ammonia or primary aliphatic amines as binucleophiles, for the eco-friendly and atom-economical synthesis of diverse and functionalized 2-pyridones 3 with potential biological activity in …
