The chiral formylferrocenes 2-5 have been readily prepared in good yields by ortho-lithiation of the TMS-blocked orunblocked aminoferrocenes and subsequent reaction with DMF. The stereochemistry of the reaction of 2 with organometallic reagents has been examined. Reactions of 2 with Grignard and org
