Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Computed Properties of C3H2N2O3. Introducing a new discovery about 1121-13-7, Name is 4-Nitroisoxazole
4-Aminoisoxazoles can be acylated with a wide variety of activated carboxylic acids.Hydrogenation of the resulting amides gives alpha-(acylamino)enaminones, which cyclize to 4(5)-acylimidazoles upon treatment with base.This method allows for the synthesis of acylimidazoles with a wide range of substituents at C-2.Utilization of N-substituted 4-aminoisoxazoles in the same sequence of reactions yields 1-substituted 5-acylimidazoles, a substitution pattern not otherwise easily prepared.Treatment of alpha-(acylamino)enaminones, derived from N-unsubstituted isoxazoles, with primary amines leads to incorporation of the amine at the beta-position with concomitant expulsion of ammonia.This sequence efficiently yields 1-substituted and 1,2-disubstituted 4-acylimidazoles but does not give satisfactory yields of 5-substituted 4-acylimidazoles due to steric inhibition of the amine exchange.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C3H2N2O3, you can also check out more blogs about1121-13-7
