Eco-friendly multi-component synthesis of γ-spiroiminolactones in water
Safaei, Hamid Reza,Shekouhy, Mohsen
, p. 1020 - 1029 (2018/01/17)
γ-Spiroiminolactone derivatives can be synthesized through an one-pot three-component reaction of cyclic carbonyl compounds (isatin, acenaphthoquinone, ninhydrin), activated a-methylene carbonyl groups and isocyanides in water using sodium dodecyl sulfate (SDS) as a commercially available and cheap surfactant compound. All products were obtained in good to excellent yields without formation of any by-products in water as a green and benign reaction medium. Moreover, presented method was successfully applied for the synthesis of some novel bis(spiroiminolactone) derivatives.
Highly efficient, one-pot synthesis of novel bis-spirooxindoles with skeletal diversity: Via sequential multi-component reaction in PEG-400 as a biodegradable solvent

A green and efficient one-pot, sequential, multi-component protocol has been developed for the synthesis of some novel symmetrical bis-spirooxindole derivatives from the reaction of isatins, dihalides, malono derivatives and C-H activated carbonyl compoun
Novel mono- and bis(spiro-2-amino-4 H -pyrans): Alum-catalyzed reaction of 4-hydroxycoumarin and malononitrile with isatins, quinones, or ninhydrin
Karimi, Ali Reza,Sedaghatpour, Fahime
experimental part, p. 1731 - 1735 (2010/07/03)
Some new mono- and bis(spiro-2-amino-4H-pyrans) are synthesized by the multicomponent condensation reaction of 4-hydroxycoumarin and malononitrile with isatins, ninhydrin, 9,10-phenanthrenequinone, or acenaphthenequinone. Alum was found to be a suitable and efficient catalyst for this condensation. Georg Thieme Verlag Stuttgart - New York.
