| Popis: | The structures of four products formed in the interaction of lithiated N-methylpyrazole with isoamyl nitrite are determined. One of the reaction products is found to be a 1,4-diazocine derivative–a medium-sized condensed heterocycle in which three pyrazole moieties are annulated to an eight-membered heterocycle and yet another pyrazole moiety is located in a side chain. This molecular structure of the compound blocks the transformation of the eight-membered heterocycle into the bicyclic derivative through a transannular reaction. |
