Studies on quinones. Part 32.1 Regioselective synthesis of benz[b]phenantridines related to phenantroviridone
Valderrama, Jaime A.,Gonzalez, M. Florencia,Valderrama, Claudio
, p. 6039 - 6050 (1999)
The Diels-Alder reaction of juglone (4) and bromojuglone 18 with 1- cyclohexenecarboxaldehyde dimethylhydrazone (3) is described. Through these cycloaddition reactions 8-hydroxy-1,2,3,4-tetrahydrobenz[b]phenantridin- 7,12-dione (5) was obtained in 55 and
Synthesis of Chromone-Containing Allylmorpholines through a Morita–Baylis–Hillman-Type Reaction
Chernov, Nikita M.,Shutov, Roman V.,Barygin, Oleg I.,Dron, Mikhail Y.,Starova, Galina L.,Kuz'mich, Nikolay N.,Yakovlev, Igor P.
supporting information, p. 6304 - 6313 (2018/11/10)
The first example of an unusual addition of chromone-substituted acrylic acid to enamines is described. The process shows high versatility concerning both enamines and chromones. The reaction is catalyzed by tertiary amines and is highly likely of Morita–
Palladium-catalysed amination of aryl- and heteroaryl halides using tert-butyl tetraisopropylphosphorodiamidite as an easily accessible and air-stable ligand
Roiban, Gheorghe-Doru,Mehler, Gerlinde,Reetz, Manfred T.
, p. 2070 - 2076 (2014/04/17)
The phosphorus compound tert-butyl tetraisopropylphosphorodiamidite, prepared from bis(diisopropylamino)chlorophosphine, is an excellent ligand for palladium-catalysed Buchwald-Hartwig amination of aryl- and heteroaryl chlorides and bromides. Based on its ready accessibility and air-stability, this amination protocol is a practical approach to the synthesis of industrially important aryl- and heteroarylamines. Copyright
