One Step

Some 2-hydroxy-4-methyl-6- substituted quinoline derivatives have been synthesized in an environmentally benign method from easily available 4-substituted anilines and ?-Ketoesters, under ordinary conditions. The reactions were catalyzed by aluminium chloride to afford excellent amount of the products. The usage of hazardous acids, bases and solvents have been avoided in different steps of the reactions completely, which has made this synthetic method one step advance to the existing methods.DOI: http://dx.doi.org/10.3126/jncs.v27i1.6670 J.

Component Approach

A copper(II)-catalyzed multi-component one-pot approach for the synthesis of 1,3-oxazines at room temperature is reported here. Methanol is used as the solvent as well as the carbon source. The methylene carbon of the oxazine product comes from methanol via formaldehyde. tert-Butyl hydroperoxide is used as the oxidant. The reaction uses an environmentally benign metal catalyst and oxidant. No inert atmosphere or precaution is required for the reaction. Most importantly, the reaction avoids the use of carcinogenic formaldehyde.
