NHC-catalyzed ester activation : access to sterically congested spirocyclic oxindoles via reaction of α-aryl esters and unsaturated imines
Carboxylic esters can be readily obtained at low cost. Therefore, asymmetric catalytic activation of esters should provide useful strategies for organic synthesis. Here we report a N-heterocyclic carbene (NHC)-mediated reaction of α-aryl acetic esters with oxindole-derived α,β-unsaturated imines. Th...
