An efficient, green and sustainable approach for the synthesis of novel polycyclic pyrrolidine-fused spirooxindole compounds was developed. The synthesis included a one-pot, three-component, domino reaction of (E)-3-(2-nitrovinyl)-indoles, isatins and chiral polycyclic α-amino acids under catalyst-free conditions at room temperature in EtOH–H2O. The salient features of this methodology are eco-friendliness

Ethylenediamine (H2NCH2CH2NH2) was found to be a highlyeffectivecatalyst for the condensation of aryl aldehydes with nitromethane (or nitroethane). When 1%–2% (mol%) of ethylenediamine was used as the catalyst, the one‐pot reaction of aryl aldehydes with nitromethane (or nitroethane) by refluxing for 3–10 h efficiently afforded various arylnitroalkenes 1a–1y in 85%–97% yields.

efficient and simple strategy has been developed to synthesize various substituted nitroalkenesinvolving a cooperativecatalytic system of FeCl3 and piperidine. This dual catalytic protocol simultaneously activates both electrophile and nucleophile and works under mild reaction conditions so that many sensitive functional groups were tolerated. Moreover, this cooperativecatalytic reaction is also suitable
