- This article presents the research project “Searching for a New National Identity: The Construction of Swedish Cultural Memory in Carl Snoilsky’s Poems Svenska bilder”, and functions as an introduction to the four subsequent articles in this issue of Studia Litteraria, which are the result of the project. The principal aim of the project was a comprehensive analysis of the construction of cultural memory in Carl Snoilsky’s cycle of poems Svenska bilder (Swedish Pictures) for many decades being part of the core canon of Swedish literature, but which remains largely forgotten today. In part one, the article outlines the complex process of the creation and publication of Svenska bilder. It also reviews the state of research on Snoilsky’s cycle, justifying the need for new theoretical perspectives. In part two, the article analyses ways in which national memory is portrayed in Svenska bilder at different intra- and extranarrative levels, arguing that cultural memory and its preservation are among the central themes of the cycle. In part three, the article illuminates the construction of cultural memory in Svenska bilder as an example of nineteenth-century European cultural memory. The article considers three features, typical of nineteenth-century collective memory culture, to be particularly important for Snoilsky’s poems: subjectivisation, historicisation, and nationalisation. In part four, the article discusses Svenska bilder as an attempt to democratise the model of Swedish national memory created by the Romantics. The article argues that the cultural memory in Svenska bilder in many ways reflects the liberal ideas of the second half of the nineteenth century advocated by Snoilsky. In part five, the article examines the place of Polishness in the construction of Swedish cultural memory in Svenska bilder. Although Snoilsky considered himself a friend of Poland and an advocate for the Polish independence movements, in his cycle he assigns Polishness the role of the negative Other that serves to consolidate a positively characterised Swedish national identity. The article concludes with a short presentation of the four articles that are the fruits of the presented project.

Tidskriftsartikel (refereegranskat)abstract
- The highly enantioselective organo-co-catalytic aza-Morita–Baylis–Hillman (MBH)-type reaction between N-carbamate-protected imines and α,β-unsaturated aldehydes has been developed. The organic co-catalytic system of proline and 1,4-diazabicyclo[2.2.2]octane (DABCO) enables the asymmetric synthesis of the corresponding N-Boc- and N-Cbz-protected β-amino-α-alkylidene-aldehydes in good to high yields and up to 99% ee. In the case of aza-MBH-type addition of enals to phenylprop-2-ene-1-imines, the co-catalytic reaction exhibits excellent 1,2-selectivity. The organo-co-catalytic aza-MBH-type reaction can also be performed by the direct highly enantioselective addition of α,β-unsaturated aldehydes to bench-stableN-carbamate-protected α-amidosulfones to give the corresponding β-amino-α-alkylidene-aldehydes with up to 99% ee.The organo-co-catalytic aza-MBH-type reaction is also an expeditious entry to nearly enantiomerically pure β-amino-α-alkylidene-amino acids and β-amino-α-alkylidene-lactams (99% ee). The mechanism and stereochemistry of the chiral amine and DABCO co-catalyzed aza-MBH-type reaction arealso discussed.

Tidskriftsartikel (refereegranskat)abstract
- The development, scope, and application of the highly enantioselective organocatalytic aziridination of α,β-unsaturated aldehydes is presented. The aminocatalytic azirdination of α,β-unsaturated aldehydes enables the asymmetric formation of β-formyl aziridines with up to >19:1 d.r. and 99 % ee. The aminocatalytic aziridination of α-monosubstituted enals gives access to terminal α-substituted-α-formyl aziridines in high yields and up to 99 % ee. In the case of the organocatalytic aziridination of disubstituted α,β-unsaturated aldehydes, the transformations were highly diastereo- and enantioselective and give nearly enantiomerically pure β-formyl-functionalized aziridine products (99 % ee). A highly enantioselective one-pot cascade sequence based on the combination of asymmetric amine and N-heterocyclic carbene catalysis (AHCC) is also disclosed. This one-pot three-component co-catalytic transformation between α,β-unsaturated aldehydes, hydroxylamine derivatives, and alcohols gives the corresponding N-tert-butoxycarbonyl and N-carbobenzyloxy-protected β-amino acid esters with ee values ranging from 92-99 %. The mechanisms and stereochemistry of all these catalytic transformations are also discussed.
