Bioinspired nonheme iron-catalyzed enantioselective cis-dihydroxylation meets the requirement of the modern synthetic chemistry from atomic economy, green chemistry and sustainable development perspectives. However, nonheme iron-catalyzed enantioselective cis-dihydroxylation is much underdeveloped because of the formidable challenges of controlling chemo- and enantioselectivities and product selectivity caused from the competitive epoxidation, cis-dihydroxylation and overoxidation reactions. Herein, we disclose a biologically inspired nonheme iron complex-catalyzed enantioselective cis-dihydroxylation of multi-substituted acrylates using hydrogen peroxide (H2O2) as a terminal oxidant by controlling the non-ligating or weakly ligating counterions of iron(II) complexes; we have demonstrated a dramatic counteranion effect on the enantioselective cis-dihydroxylation of olefins by H2O2 catalyzed by nonheme iron complexes. A range of structurally disparate alkenes are transformed to the corresponding syn-2,3-dihydroxy esters in practically useful yields with exquisite chemo- and enantioselectivities (up to 99% ee). Given the mild and benign nature of this biologically inspired oxidation system and the ubiquity and synthetic utility of enantioenriched syn-2,3-dihydroxy esters in pharmaceuticals candidates and natural products, we expect that this strategy to some extent can serve as a promising compliment to the well-known Sharpless asymmetric dihydroxylation.
