Chiral bicyclic guanidine-catalysed conjugate addition of α-fluoro-β-ketoesters to cyclic enones
By utilising a chiral bicyclic guanidine as catalyst and triethylamine as additive, the first asymmetric Michael addition of α-fluoro-β-ketoesters to various cyclic enones has been successfully developed, affording a variety of Michael adducts with potential synthetic utilities with satisfactory ste...

description | By utilising a chiral bicyclic guanidine as catalyst and triethylamine as additive, the first asymmetric Michael addition of α-fluoro-β-ketoesters to various cyclic enones has been successfully developed, affording a variety of Michael adducts with potential synthetic utilities with satisfactory stereoselectivity (up to 94 % ee and 4.3 : 1 dr). |
