An Improved Procedure for the Palladium-Catalyzed Oxidative Carbonylation of β-Amino Alcohols to Oxazolidin-2-ones
摘要:
A highly efficient oxidative cyclocarbonylation of beta-amino alcohols and 2-aminophenol to oxazolidin-2-ones has been achieved by using PdI2 in conjunction with KI as the catalytic system in DME under relatively mild conditions (100 degreesC and 20 atm of a 4:1 mixture of CO and air).
