Gold-Mediated Synthesis and Functionalization of Chiral Halopyridones
摘要:
A rapid and efficient one-step halopyridone synthesis has been developed based on gold-catalyzed cyclization of beta-amino-ynone intermediates and halodeauration process.
Enantiospecific Synthesis of Pyridinones as Versatile Intermediates toward Asymmetric Piperidines
摘要:
The enantiospecific syntheses of pyridinones from amino acids via a gold-catalyzed strategy are reported. Excellent stereocontrol was observed during the cyclization. This approach provides a straightforward tool for further synthetic applications toward piperidines.
