Mild and Regiospecific Reduction of Masked 1,3-Dicarbonyl Derivatives to Monocarbonyl Compounds and Primary and Secodary Amines
The regiospecific reduction of masked 1,3-dicarbonyl compounds to the corresponding saturated monocarbonyl 3 or iminic 4 compounds via 3-amino-2-alkenimines 1 is described.The formation of 3 and 4 can be explained in terms of a double reduction process from 1.A simple method for the synthesis of primary and secondary amines 6 is also described.
