Highly efficient organocatalytic one-pot enantioselective synthesis of (R)-2-aryl-2,3-dihydro-4-quinolones from o-aminoacetophenones and aryl aldehydes were developed. The approach was characterized by being metal free, solvent free and protecting group free. Variety of 2-aryl-2,3-dihydro-4-quinolones could be obtained in good yields up to 99% ee. In the experiment, the researchers used many compounds, for example, 1-(6-Aminobenzo[d][1,3]dioxol-5-yl)ethanone (cas: 28657-75-2Application of 28657-75-2).
1-(6-Aminobenzo[d][1,3]dioxol-5-yl)ethanone (cas: 28657-75-2) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.Application of 28657-75-2
