Application of the chiral auxiliary [(eta(5)-C5H5)Fe(CO)(PPh(3))] to the stereoselective formation of 4-substituted-1,4-dihydronicotinoyl complexes
In solution regio-and stereoselective additions of nucleophiles to (RS)-[(η5-C5H5)Fe(CO) (PPh3)CO-3-pyridyl] (1) occur at C-4 to give the corresponding nitrogen-stabilised anions. Subsequent quenching of these anions by a proton, a chloroformate or dimethyl sulfate gives the corresponding 1,4-dihydr...
