Asymmetric Carboalkoxyalkylidenation with a Chiral Horner-Wadsworth-Emmons Reagent
摘要:
The asymmetric carboalkoxyalkylidenation of 4-substituted cyclohexanones was effected by the use of chirally modified Horner-Wadsworth-Emmons (HWE) reagents in good yields (78-82%) as well as high levels of enantioselectivity (78-86% ee).
