摘要：

(Chemical Equation Presented) Toss the olefin into the porphyrin: The development of chiral cobalt(II)-porphyrin catalysts by straightforward coupling processes has made possible the additions of diazocarbonyl compounds to a broad spectrum of olefins to access functionalized cylopropanes. The cyclopropanation reactions demonstrate high product yields, exceptional diastereoselectivity, and excellent enantiocontrol. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
