4,4-Dimethyl-3,5,8-trioxabic-yclo[5,1,0]Octane Chemical Properties,Uses,Production
Chemical Properties
Clear colorless to yellow liquid
Uses
4,4-Dimethyl-3,5,8-trioxabicyclo[5.1.0]octane is used in the CO2-mediated formation of chiral carbamates from meso-epoxides via polycarbonate intermediates and amine nucleophiles, which opens up a wide a wide range of CO2-based carbamate scaffolds with excellent yields and 99% enantiomeric excess.
Application
4, 4-dimethyl-3,5, 8-trioxane [5,1,0] octane is a key intermediate in the preparation of gadobinol. As a meso epoxide, it could be used to obtain optically pure ABT derivatives through Ti(IV)/BINOL catalyzed asymmetric aminolysis[1].
