Application
Dimethyl propargylmalonate can be used as a reactant to synthesize:
- Nitro methylenecyclopentanes by [3+2] annulation reaction with various nitroalkenes in the presence of Triton B.
- Propargylmalonamides intermediates, applicable in the preparation of ″click BOX″ ligands by copper-catalyzed cycloaddition and oxazoline ring formation reaction.
- Cyclopentene derivatives by reacting with various α, β-unsaturated ketones using a combination of organocatalysts and transition metal catalysts.
