Enaminones are used as the key intermediates to construct heterocyclic compounds with various bioactivities. In this study, a simple and efficient approach for the synthesis of enaminones via amination of propargyl alcohols was developed. Under the catalysis of Ag2CO3, the reaction proceeded smoothly to afford the desired products in good yields. Preliminary mechanism experiments showed that Ag2CO3 played an essential role in the procedure of the reaction.

The Br?nsted acid catalyzed Meyer-Schuster reaction of hemiaminals was studied for the stereoselective synthesis of β-enaminones. Hemiaminals were formed from propargyl aldehydes (or the oxidation of propargyl alcohols) and amines in the presence of Br?ns

A nickel-phosphine complex was found to be effective as the catalyst for the transformation of alcohols into β-enaminones, which was successively converted into γ-amino alcohols by a conventional reductant. The sequential transformation is equivalent to the carbon-nitrogen bond formation at the γ-position of saturated alcohols. Georg Thieme Verlag Stuttgart · New York.
Studies with Enaminones: The reaction of enaminones with Aminoheterocycles. A route to Azolopyrimidines, Azolopyridines and Quinolines
