2,2-Dimethylcyclopentanone Chemical Properties,Uses,Production
Chemical Properties
Clear colorless to yellow liquid
Uses
2,2-Dimethylcyclopentanone enolate may be used as starting reagent in the enantioselective synthesis of chiral phosphines belonging to the P-aryl-2-phosphabicyclo[3.3.0]octane family (PBO). It may be used in the synthesis of:
- 2,6,6-trimethyl-2-azaspiro[4.4]nonane-1,3-dione, a spirosuccinimide moiety of asperparaline A
- novel spiropentanopyrrolizidine oxime alkaloids, namely 2′,3′,5′,6′,7′,7a′-hexahydro-2,2-dimethylspirocyclopentane-1
- δ,δ-dimethyl-δ-valerolactone, via Baeyer-Villiger oxidation
