| Abstract: | Reactions of alkyl 3-bromo-3-nitroacrylates with cyclic CH-acids, Meldrum’s acid or 3-methyl-1-phenylpyrazol-5-one, afford new spiro-fused 2-nitrocyclopropanecarboxylates. In the case of Meldrum’s acid, the products are formed as individual diastereomers. The obtained experimental results are confirmed by quantum chemical calculations (B3LYP/6-311+G(d,p) taking into account solvent effects). |
