An unusual palladium-catalyzed carbonylative cyclization of β-bromovinyl aldehydes leading to lactones
摘要:
beta-Bromovinyl aldehydes are carbonylatively cyclized under carbon monoxide pressure in MeCN at 100 degrees C in the presence of a catalytic amount of a palladium catalyst along with a base to give the corresponding lactones in high yields. (c) 2006 Elsevier Ltd. All rights reserved.
