Synthesis of new azocine derivatives and their functionalization by nucleophilic addition to their iminium salts
Badaro Trindade, Angela Cristina Leal,Dos Santos, Daniela Cristina,Gil, Laurent,Marazano, Christian,Pereira De Freitas Gil, Rossimiriam
, p. 1052 - 1057 (2007/10/03)
A route to the eight-membered nitrogen heterocycles 20a,b is described starting from the 3-alkyl-N-benzylpyridinium salts 14a,b. These azocine derivatives were converted into their respective iminium salts 11 by treatment with methanesulfonic acid. A stud
An access to some functionalized azocine derivatives
Gil,De Freitas Gil,Dos Santos,Marazano
, p. 6067 - 6069 (2007/10/03)
The syntheses, from readily accessible 3-alkyl-4-methoxy-l,3,4,5-tetrahydropyridine 1, of functionalized 1,6,7,8-tetrahydroazocine 7 and 1,2,7,8-tetrahydroazocine 9 are reported. (C) 2000 Published by Elsevier Science Ltd.
A novel Diels-Alder approach to hydroisoquinolines
Baldwin, Jack E.,Spring, David R.,Whitehead, Roger C.
, p. 5417 - 5420 (2007/10/03)
A synthetic approach to functionalised hydroisoquinoline rings, using dihydropyridinium ions as dienophiles in the Diels-Alder reaction, is described.
3-Alkyl-1,6-dihydropyridines from 3-alkyl 5,6-dihydro-pyridinium salts. Implications in the biosynthesis of some macrocyclic marine alkaloids
Gil,Gateau-Olesker,Marazano,Das
, p. 707 - 710 (2007/10/02)
Additions of salts 1 and dihydropyridines 2 in an intramolecular manner have been involved in the biosynthesis of some macrocyclic alkaloids such as manzamines, sarain A and halicyclamine A, recently isolated from sponges. We report conditions for the dep
