Double Asymmetric Hydrogenation of (E)‐2‐Substituted‐4‐oxo‐2‐alkenoic Acids: An Efficient Synthesis of Chiral α, γ‐Disubstituted γ‐Butyrolactones
European Journal of Organic Chemistry(2022)
摘要
Optical pure α, γ‐disubstituted γ‐butyrolactones moieties are versatile building blocks for the synthesis of many drugs and natural products. Herein we report a straightforward and efficient approach to afford a series of chiral α, γ‐disubstituted γ‐butyrolactones with excellent results (up to 98 % yield, up to >99 : 1 d.r., and up to >99 % ee) through the double asymmetric hydrogenation of the (E)‐2‐methyl‐4‐oxo‐2‐alkenoic acids utilizing the rhodium/JosiPhos catalytic system.
