A one-pot multicomponent domino reaction between 2-isocyanoethylindoles and isocyanates for the diastereoselective construction of polycyclic bispiroindolines was developed. Fused polycyclic bispiroindolines containing two contiguous spiral atoms were afforded in moderate to good yields with excellent regio- and diastereoselectivities through a four-component Ugi-type reaction (U-4CR) under mild conditions.

C-Alkylation of 2-hydroxy-1,4-naphthoquinone to various nitroolefins was achieved under catalyst-free employing 'on water' conditions. The mechanism for the formation can be explained on the basis of dual activation of nitroalkene and 2-hydroxy-1,4-naphth
