A one-pot-three-step route to triazolotriazepinoindazolones from oxazolino-2H-indazoles

Conrad W.E.; Rodriguez K.X.; Nguyen H.H.; Fettinger J.C.; Haddadin M.J.; Kurth M.J. (WASHINGTON1155 16TH ST, NW, WASHINGTON, DC 20036 USA, 2012)

A one-pot-three-step method has been developed for the conversion of oxazolino-2H-indazoles into triazolotriazepinoindazolones with three points of diversity. Step one of this process involves a propargyl bromide-initiated ...
Acid and base catalyzed Davis-Beirut reaction: Experimental and theoretical mechanistic studies and synthesis of novel 3-amino-2H-indazoles

Avila B.; El-Dakdouki M.H.; Nazer M.Z.; Harrison J.G.; Tantillo D.J.; Haddadin M.J.; Kurth M.J. (OXFORDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2012)

The Davis-Beirut reaction, which provides an efficient synthesis of 2H-indazoles and, subsequently, indazolones, is shown to proceed rapidly from o-nitrosobenzaldehyde and primary amines under both acid and base catalysis. ...
Davis-Beirut reaction: Route to thiazolo-, thiazino-, and thiazepino-2 h -indazoles

Farber K.M.; Haddadin M.J.; Kurth M.J. (American Chemical Society; WASHINGTON1155 16TH ST, NW, WASHINGTON, DC 20036 USA, 2014)

Methods for the construction of thiazolo-, thiazino-, and thiazepino-2H-indazoles from o-nitrobenzaldehydes or o-nitrobenzyl bromides and S-trityl-protected 1°-aminothioalkanes are reported. The process consists of formation ...
The davis-beirut reaction: A novel entry into 2h-indazoles and indazolones. Recent biological activity of indazoles

Haddadin M.J.; Conrad W.E.; Kurth M.J. (SHARJAHEXECUTIVE STE Y-2, PO BOX 7917, SAIF ZONE, 1200 BR SHARJAH, U ARAB EMIRATES, 2012)

A novel, easy method for the syntheses of richly diversified 2H-indazoles and indazolones, called the Davis-Beirut reaction, and other recent 2H-indazole synthetic routes are briefly reviewed. An update on the biological ...
The Davis-Beirut reaction: N 1, N 2-disubstituted-1 H-indazolones via 1,6-electrophilic addition to 3-alkoxy-2 H-indazoles

Conrad W.E.; Fukazawa R.; Haddadin M.J.; Kurth M.J. (WASHINGTON1155 16TH ST, NW, WASHINGTON, DC 20036 USA, 2011)

A variety of electrophiles (anhydrides, acid chlorides, carbonochloridates, sulfonyl chlorides, and alkyl bromides) react with 3-methoxy-2H-indazole (1a), benzoxazin[3,2-b]indazole (1d), and oxazolino[3,2-b]indazole (1e) ...
