Abstract
The asymmetric addition of diazoacetylferrocene to styrene derivatives to give optically active cyclopropyl acetylferrocenes (ee up to 96%) was carried out using chiral ruthenium porphyrins as homogeneous catalysts. Intermolecular N–H functionalization of anilines and amino esters by means of carbenoid-induced N–H insertion was also observed using tetraphenylporphyrin iron chloride as catalyst.
