“…Bezüglich der Struktur des Doppelfünfring-H-Chelates war von Interesse, wie sich das 1 H-NMR-Spektrum ändert, wenn eine solche Anordnung nicht mehr mçglich ist. Dazu wurde das bekannte 2-Brom-3-oxosulfon 41 [37] nach der Na 2 CS 3 -Methode umgesetzt (Schema 9).…”

“…The production of the O-acyl derivatives 128, the alkyl 129 and silyl 131 ethers of enols, the enamines 132, and the 2-bromo 130 and 4-alkyl 133 derivatives was described in [46] The reactions of the carbonyl group in dihydrothiophen-3-one 1,1-dioxide were investigated by the authors of [43]. For the dihydrothiophen-3-one 1,1-dioxide substituted at position 4 O-acylation leading to the formation of the products 135 and 136, dehydrogenation leading to the product 75, opening of the thiophene ring leading to the product 138, and reaction with nitrogen-containing nucleophiles leading to the formation of the products 139 and 140 were investigated.…”

“…Acid hydrolysis leads to the final product 50. The sulfolene 60 can be converted into the 3-oxosulfolane 50 by the addition of bromine at the double bond and its subsequent elimination by the action of sodium alkoxide [46]. The readily obtainable 3-hydroxybenzothiophene 70 can be oxidized to benzothiophen-3(2H)-one dioxide 69 under the conditions of the Prilezhaev reaction [48].…”

“…In order to study the elimination of acyl fragment in the reaction of BHAs with polycarbonyl compounds we synthesized cyclic 1,3-ketoaldehyde -2-formyl-3-ketosulpholane 2e by acylation of useful synthetic block, 3-sulpholanone 20 19 according to Claisen procedure 18. . We assumed that the structural rigidity of molecule 2e will prevent the rupture of the C-C bond in the reagent, so that the reaction product will be imidazolidinylidene with two electron-withdrawing substituents at the terminal atom of enamine fragment.…”
