• 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. ...

• 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 ...

• Stereoselective Synthesis of Spiro-Decalin Oxindole Derivatives via Sequential Organocatalytic Michael-Domino Michael/Aldol Reaction 

  Straminelli, Leonardo; Vicentini, Francesco; Di Sabato, Antonio; Montone, Carmela Maria; Cavaliere, Chiara; Rissanen, Kari; Leonelli, Francesca; Vetica, Fabrizio (American Chemical Society (ACS), 2022)

  A highly stereoselective procedure for the synthesis of spiro-polycyclic oxindoles bearing five contiguous stereogenic centers including two tetrasubstituted carbons has been developed. Under sequential organocatalysis ...

• Asymmetric Synthesis of Spirocyclic β‐Lactams via Copper‐Catalyzed Kinugasa/Michael Domino Reactions 

  Shu, Tao; Zhao, Long; Li, Sun; Chen, Xiang-Yu; von Essen, Carolina; Rissanen, Kari; Enders, Dieter (Wiley, 2018)

  The first copper‐catalyzed highly chemo‐, regio‐, diastereo‐, and enantioselective Kinugasa/Michael domino reaction for the desymmetrization of prochiral cyclohexadienones is described. In the presence of a chiral copper ...

• Stereocontrol in Diphenylprolinol Silyl Ether Catalyzed Michael Additions : Steric Shielding or Curtin-Hammett Scenario? 

  Földes, Tamás; Madarász, Ádám; Révész, Ágnes; Dobi, Zoltán; Varga, Szilárd; Hamza, Andrea; Nagy, Péter R.; Pihko, Petri; Pápai, Imre (American Chemical Society, 2017)

  The enantioselectivity of amine-catalyzed reactions of aldehydes with electrophiles is often explained by simple steric arguments emphasizing the role of the bulky group of the catalyst that prevents the approach of ...
