From cyclopentadiene to isoxazoline-carbocyclic nucleosides: a rapid access to biological molecules through aza-Diels-Alder reactions
Quadrelli, Paolo,Piccanello, Andrea,Mella, Mariella,Corsaro, Antonino,Pistarà, Venerando
, p. 3541 - 3547 (2008)
A rapid access to carbocyclic nucleosides containing a fused isoxazoline ring is proposed through the Grieco cycloaddition of cyclopentadiene to iminium salts. The prolific elaboration of the isoxazoline cycloadducts allowed preparation of the target amin
Halogenation of 2-alkyl-2-azabicycloalkenes as a method for the synthesis of stable aziridinium salts of a new class
Sosonyuk,Bulanov,Leshcheva,Zyk
, p. 1254 - 1261 (2002)
Addition of bromine and potassium dihaloiodates(I) to 2-alkyl-2-azabicyclo[2.2.1]hept-5-enes and 2-alkyl-2-azabicyclo[2.2.2] oct-5-enes affords quaternary ammonium salts containing the aziridine ring and the polyhalide anion. The possibility of using thes
Polysulfones of new structural types as perspective antioxidant agents
Gorbunova, Marina,Anikina, Lada
, p. 655 - 661 (2013)
A series of polysulfones of new structural types on the basis of azanorbornenes, 2,2-diallyl-1,1,3,3-tetraethylguanidiniumchloride and tris(diethylamino)diallylaminophosphonium salts were obtained by free radical polymerization reaction. Their antioxidant
Chlorination/cyclodehydration of amino alcohols with SOCl2: An old reaction revisited
Xu, Feng,Simmons, Bryon,Reamer, Robert A.,Corley, Edward,Murry, Jerry,Tschaen, David
, p. 312 - 315 (2008/09/17)
(Chemical Equation Presented) A simple, one-pot preparation of cyclic amines via efficient chlorination of amino alcohols with use of SOCl2 has been developed. This approach obviates the need for the classical N-protection/O-activation/cyclization/deprotection sequence commonly employed for this type of transformation. The reaction pathways and the general scope of this method have also been investigated.
A 1,3-Diaza-Claisen rearrangement that affords guanidines
Bowser, Amy M.,Madalengoitia, Jose S.
, p. 3409 - 3412 (2007/10/03)
(Chemical Equation Presented) N-Alkyl-N′-tosylthioureas activated by EDCI react with azanorbonenes at room temperature through a 1,3-diaza-Claisen rearrangement, affording highly substituted, bicyclic guanidines in moderate to good yields.

ROLE REVERSAL IN THE CYCLOCONDENSATION OF CYCLOPENTADIENE WITH HETERODIENOPHILES DERIVED FROM ARYL AMINES AND ALDEHYDES: SYNTHESIS OF NOVEL TETRAHYDROQUINOLINES
Grieco, Paul A.,Bahsas, Ali
, p. 5855 - 5858 (2007/10/02)
Immonium ions derived from aryl amines and aldehydes function not as heterodienophiles but rather as heterodienes in the presence of cyclopentadiene giving rise to novel tetrahydroquinolines.
