Mechanistic Investigations of the Pd-Catalyzed Hydrogenolysis of Ketene Heterodimer β-Lactones

Panda, Manashi,Mondal, Mukulesh,Chen, Shi,Ibrahim, Ahmad A.,Twardy, Dylan J.,Kerrigan, Nessan J.

, p. 5752 - 5764 (2020/09/07)

Catalytic hydrogenolysis of the Z-isomer of a series of aryl-substituted ketene heterodimer β-lactones facilitated access to deoxypropionate derivatives with a dr ranging from 54:46 to 86:14, favoring the anti-isomer, and with excellent transfer of chiral
