Stereoselective synthesis of α-ylidene-β-dicarbonyl compounds: A mild PhI(OAc)2-mediated dehydrogenation process

Fan, Liyan,Chen, Wen,Tang, Kunshan,Wu, Dongbei

, p. 940 - 942 (2012)

PhI(OAc)2-mediated dehydrogenation of α-alkyl-β-dicarbonyl compound has been developed to afford α-ylidene-β- dicarbonyl compounds with high stereoselectivity under mild conditions. This process provides a complementary entry to stereoselectivity for the Knoevenagel reaction.
