Asymmetric Synthesis of γ-Hydroxy α-Enones by 1,8-Diazabicyclo[5.4.0]undec-7-ene-Catalyzed Stereoselective Rearrangement of Chiral α-Sulfinyl Enones
摘要:
The asymmetric rearrangement of optically active a-sulfinyl enone 1 induced by catalytic DBU and triphenylphosphine gave optically active gamma-hydroxy alpha-enone derivatives (up to 99% ee) in good yield following treatment with aqueous hydrogen peroxide.
