  • Patent number: 6093825
    Abstract: Methods for conversion of anilines to 1,2-dihydroquinolines. 1,2-dihydroquinoliiies are generated from combining an aniline, a silylating agent, and further condensing with a ketone in the presence of a catalyst. In one aspect, the silylation of the aniline may be performed in a one-step synthesis by adding the silylating, agent to the same reaction vessel as the ketone, aniline, and catalyst. In a second aspect, the 1,2-dihydroquinoline is generated in a two-step synthesis where an N-silyl aniline is formed prior to the addition of the ketone and catalyst.
