Chemoselective Asymmetric N‐Allylic Alkylation of Indoles with Morita–Baylis–Hillman Carbonates

Give me convenience: The title transformation has been developed by employing metal-free catalysis of modified cinchona alkaloids. Moderate to excellent enantioselectivities have been achieved for a broad array of substrates (see scheme). This reaction also provides a convenient method to prepare multiply functionalized pyrrolo[1,2-a]indole and pyrrolo[3,2,1-ij]quinoline derivatives.
