Multifunctional 1,3-diphenylguanidine for the carboxylative cyclization of homopropargyl amines with CO2 under ambient temperature and pressure?
Chemical Communications Pub Date: 2019-10-21 DOI: 10.1039/C9CC07671A
Abstract
Herein, we report that 1,3-diphenylguanidine (DPG) could be utilized for the carboxylative cyclization of homopropargyl amines with CO2 under ambient temperature and pressure, in combination with AgSbF6, which enabled the synthesis of both chiral and achiral 2-oxazinones efficiently. A mechanistic study revealed that the multi-functionality of DPG is critical to the success of the reaction.
