Msutu, Ath’enkosi published the artcileAcetals: a new organocatalysis chemotype for one-pot enantioselective α-amination, Name: 1,4-Dioxaspiro[4.5]decane, the publication is Tetrahedron Letters (2014), 55(14), 2295-2298, database is CAplus.
Conditions are described for one-pot Bronsted acid and organocatalyzed enantioselective α-amination of acetals and associated functionalities. Of the organocatalysts screened, proline tetrazole gave the highest ee, while aqueous monochloroacetic acid proved to be the best Bronsted acid activator regarding minimizing racemization and maximizing product yield. The reaction opens up the way for using masked carbonyl functionalities in organocatalysis.
