The stereospecific Fe-catalyzed arylation of enol tosylates with Grignard reagents was reported for the synthesis of Z- and E- tri/tetrasubstituted acrylates (Ar)(R)C=C(CO2R1)(R2) [R = Me, i-Pr, Ph, etc.; R1 = Me, Et; R2 = H, Me, Ph; Ar = Ph, 2-CNC6H4, 2-thienyl, etc.]. Various tri- or tetrasubstituted Z or E-enol tosylates of β-keto esters were arylated using common and Knochel-type Grignard reagents with complete stereofidelity. The precursors for Z/E-zimelidine, tamoxifen and other bioactive compounds were facilely prepared without precious and toxic transition metals.
