Novel water-soluble, copolymer capped zinc oxide nanorods with high photocatalytic activity for degradation of organic pollutants from water

Six-component synthesis and biological activity of novel spiropyridoindolepyrrolidine derivatives: A combined experimental and theoretical investigation

“…Therefore, high-efficiency methods or actively synthesized compounds were needed for eliminating or decreasing these problems. In recent years, we studied about enhancing new and easy processes for the generation of important heterocyclic compounds ( Babizhayev et al, 2004 ; Ebrahimi, et al, 2008 ; Kassaee et al, 2010 ; Yavari et al, 2010 ; Khandan-Barani et al, 2011 ; Rustaiyan, et al, 2011 ; Rustaiyan, et al, 2011 ; Shahvelayati et al, 2012; Ezzatzadeh et al, 2012 ; Hassanabadi and Khandan-Barani, 2013 ; Masoodi, et al, 2013 ; Abdolmohammadi, 2014b ; Maghsoodlou, et al, 2014 ; Azizi et al, 2015 ; Hajinasiri et al, 2015 ; Khandan-Barani et al, 2015 ; Balar et al, 2016 ; Balar et al, 2016 ; Ghambarian et al, 2016 ; Soleimani Amiri, et al, 2016 ; Ghambarian et al, 2017 ; Koohi, et al, 2017 ; Salehi Borban et al, 2017 ; Shahvelayati et al, 2017 ; Soleimani-Amiri et al, 2018 ; Abdolmohammadi and Hossaini, 2019 ; Ghashghaee et al, 2019 ; Hekmatara et al, 2019 ; Mohammadi, et al, 2019 ; Seifi Mansour et al, 2019 ; Abdolmohammadi et al, 2020a ; Ghashghaee et al, 2020a ; Ghashghaee et al, 2020b ; Shafaei et al, 2020 ; Ghavidel, et al, 2021 ; Zare Davijani et al, 2022b ). In this research, initially, a green procedure was employed for the generation of new spiropyridoindolepyrrolidines 7 via MCRs of isatins 1 , acetyl chloride 2 , secondary amines 3 , vinilidene Meldrum’s acid 4 , primary amines 5, and malononitrile 6 in an aqueous medium at room temperature in the vicinity of Ag/Fe 3 O 4 /CdO@MWCNT MNCs as an organometallic catalyst in aqueous media at room temperature ( Scheme 1 ).…”
