The focus of this paper is on the modal uses of verb forms and the contribution of shifters (aujourd"hui "today", ici "here") to polyphony. The alternation between indicative and subjunctive and the modal use of the imperfect will be studied from a pragmatic point of view. The imperfect enables the opening of another speaker deixis, without requiring the naming of the other deictic center. Imperfect verb forms can indicate double deixis, allowing the speaker to refer to a source of the communicated information without, however, naming this source.

Syntheses of thiazolidine-fused heterocycles via exo-mode cyclizations of vinylogous N-acyliminium ions incorporating heteroatom-based nucleophiles have been examined and discussed. The formation of (5,6)-membered systems was feasible with all nucleophiles tried (O, S and N), while the closing of the five-membered ring was restricted to O- and S-nucleophiles. The closure of a four-membered ring failed. Instead, the bicyclic (5,6)-membered acetal derivative and the tricyclic system with an eight-membered central ring were obtained from the substrates containing O and S nucleophilic moieties, respectively. The reaction outcome and stereochemistry are rationalized using quantum chemical calculations at B3LYP/6-31G(d) level. The exclusive cis-stereoselectivity in the formation of (5,6)- and (5,5)-membered systems results from thermodynamic control, whereas the formation of the eight-membered ring was kinetically controlled.

Der Beitrag zeichnet die Beziehungen zwischen dem Dichterpaar Wolfgang Hilbig und Natascha Wodin nach, die auch aufgrund ihrer gemeinsamen östlichen Wurzeln zueinanderfanden. Der Vergleich der romana "Das provisorium" und "Nachtgeschwister" thematisiert beider Beziehungen. Dies wird im Beitrag referiert und mit der besonderen Perspektive der Wechselseitigkeit reflektiert.
