Abstract
We report recent progress on Au- and Pt-catalyzed cascade reactions to access complicated molecular frameworks. Reported reactions include new cyclization/cycloaddition cascades on carbonyl and epoxide substrates tethered with an allene, alkene, and alkyne. Such substrates enable Au-catalyzed cascade reactions comprising an initial cyclization to form reactive 1,n-dipole that undergoes subsequent cycloadditions with suitable dipolarophiles. © 2012 IUPAC.
