Rapid Formation of Hindered Cores Using an Oxidative Prins Process
摘要:
An unprecedented oxidative Prins transformation on phenol derivatives mediated by a hypervalent iodine reagent has been developed. This method allows a rapid access to highly substituted compact systems present in several natural products via a carbon-based addition on an aromatic core. Substitution at each ring position has been demonstrated, enabling synthesis of molecules with up to two contiguous quaternary carbon centers in good yield.

B(C6F5)3-catalyzed highly chemoselective [2+3]-cyclative diC−H functionalization of phenols tethered with propargylic ether motifs was developed for the synthesis of polycyclic compounds. Derivatizations of the phenol-OH group demonstrated the good variability of the cyclization products, indicating the potential application of this methodology in the preparation of other types of polycyclic compounds.
