## carbenes β’ cobalt β’ diazoacetates β’ enantioselectivity β’ porphyrinoids Scheme 1. The use of a cobalt(II)-porphyrin catalyst for the cyclopropanation of olefins. Electron-sufficient, electron-neutral, and electron-deficient olefins can be used.
The asymmetric addition of diazoacetophenone to styrene derivatives to give optically active cyclopropyl ketones (ee up to 86%) was carried out by using chiral ruthenium porphyrins as homogeneous catalysts.
