• Toxicological and bioactivity evaluation of blackcurrant press cake, sea buckthorn leaves and bark from Scots pine and Norway spruce extracts under a green integrated approach 

  Pap, Nora; Reshamwala, Dhanik; Korpinen, Risto; Kilpeläinen, Petri; Fidelis, Marina; Furtado, Marianna M.; Sant’Ana, Anderson S.; Wen, Mingchun; Zhang, Liang; Hellström, Jarkko; Marnilla, Pertti; Mattila, Pirjo; Sarjala, Tytti; Yang, Baoru; dos Santos Lima, Amanda; Azevedo, Luciana; Marjomäki, Varpu; Granato, Daniel (Elsevier, 2021)

  Aqueous extracts from blackcurrant press cake (BC), Norway spruce bark (NS), Scots pine bark (SP), and sea buckthorn leaves (SB) were obtained using maceration and pressurized hot water and tested for their bioactivities. ...

• Organocatalytic Oxa-Michael/Michael/Michael/Aldol Condensation Quadruple Domino Sequence : Asymmetric Synthesis of Tricyclic Chromanes 

  Kumar, Mukesh; Chauhan, Pankaj; Bailey, Stephen J.; Jafari, Ehsan; von Essen, Carolina; Rissanen, Kari; Enders, Dieter (American Chemical Society, 2018)

  An efficient and highly stereoselective one-pot, four-component synthesis of functionalized tricyclic chromanes has been achieved through an organocatalyzed quadruple domino reaction. The reaction sequence involves an ...

• N-Heterocyclic Carbene Catalyzed Quadruple Domino Reactions through α,β-Unsaturated Acyl Azolium Intermediates : Asymmetric Synthesis of Cyclopenta[c]chromenones 

  Liu, Qiang; Chen, Xiang-Yu; Puttreddy, Rakesh; Rissanen, Kari; Enders, Dieter (Wiley, VCH Verlag GmbH & Co. KGaA, 2018)

  An N‐heterocyclic carbene catalyzed domino sequence via α,β‐unsaturated acyl azolium intermediates has been developed. This strategy provides a convenient enantioselective route to functionalized tricyclic coumarin derivatives ...

• 4-Methyl/Phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-ones Synthesis : Mechanistic Pathway Study and Single-Crystal X-ray Analysis of the Intermediates 

  Sarhan, Ahmed A. M.; Haukka, Matti; Barakat, Assem; Soliman, Saied M.; Boraei, Ahmed T. A.; Sopaih, Manar; Salama, Eid E. (MDPI, 2023)

  The synthesis of 4-methyl/phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one 4 and 7 has been reported with ninhydrin via a reaction first with ethyl acetoacetate or ethyl benzoylacetate and then a reaction of the resultant ...

• The hyperspectral and smartphone technology in CBRNE countermeasures and defence 

  Kuula, Jaana (University of Jyväskylä, 2016)

  Caused by industrial and military use as well as other sources of chemical, biological, radiological, nuclear and high-yield explosive (CBRNE) materials, the global threat of weapons of mass destruction (WMDs) remains ...
