Enamines, phosphorylated, synthesis

Finally, the importance of quinolinium salts to dye chemistry accounts for the long, productive history of their synthesis. The reaction of A/-methylformanihde with ketones, aldehydes, ketone enamines, or enol acetates in phosphoryl chloride leads to high yields of /V-methylquinolinium salts (60). [Pg.392]

Azines have been prepared by initial condensation of diethoxyphosphinyIhydrazine anions with aldehydes or ketones (Scheme 9). Phosphoryl azides undergo 1,3-dipolar cycloaddition to 2-tetralone enamines to give triazolines, possibly en route to amidines. A full paper on the addition of diethyl dibromophosphoramidate to alkenes(leading to the synthesis of 2-bromoalkylamines) has appeared. ... [Pg.145]
