The synthesis of pyridopyrimidine, pyranoquinoline, and phenanthrolinederivatives can be easily and efficiently accomplished by the direct reaction of a 1-aminopenta-1,4-diene fragment, an aromatic aldehyde, and BF 3 ·OEt 2 in the absence of any metal catalyst. The notable features of this procedure are mild reaction conditions, good to high yields, and operational simplicity.

A new efficient route for the synthesis of substituted 9-deazaxanthines in excellent yields via aza-Claisen rearrangement followed by radical cyclization has been achieved. This methodology has also been applied to the synthesis of furo[3,2-d]pyrimidine.
通过氮杂-克莱森重排,然后进行自由基环化,已经获得了一种新的有效途径,用于以优异的产率合成取代的9-脱氮黄嘌呤。该方法也已经应用于呋喃并[3,2- d ]嘧啶的合成。
Palladium-catalyzed regioselective oxidative amination of alkenes: an efficient route to the synthesis of pyrrolocoumarin and pyrroloquinolone derivatives
Palladium-catalyzed IBX-induced intramolecular oxidative amination of alkenes has been utilized for the synthesis of pyrrolocoumarin and pyrroloquinolone derivatives in excellent yields in a short reaction time.
