Asymmetric Hydrovinylation of Vinylindoles. A Facile Route to Cyclo-penta[g]indole Natural Products (+)-cis-Trikentrin A and (+)-cis-Trikentrin B
Vinylindoles undergo Ni(II)-catalyzed asymmetric hydrovinylation under very mild conditions (−78 °C, 1 atmosphere ethylene, 4 mol% catalyst) to give the corresponding 2-but-3-enyl derivatives in excellent yields and enantiose-lectivities. Hydroboration of the alkene, oxidation to an acid, followed b...
