Unlocking Amides through Selective C–N Bond Cleavage: Allyl Bromide-Mediated Divergent Synthesis of Nitrogen-Containing Functional Groups
Govindan, Karthick,Chen, Nian-Qi,Chuang, Yu-Wei,Lin, Wei-Yu
, p. 9419 - 9424 (2021/11/30)
We report a new set of reactions based on the unlocking of amides through simple treatment with allyl bromide, creating a common platform for accessing a diverse range of nitrogen-containing functional groups such as primary amides, sulfonamides, primary amines, N-acyl compounds (esters, thioesters, amides), and N-sulfonyl esters. The method has potential industrial applicability, as demonstrated through gram-scale syntheses in batch and in a continuous flow system.
Nitrogen-centered radical-mediated C-H imidation of arenes and heteroarenes via visible light induced photocatalysis
Kim, Hyejin,Kim, Taehoon,Lee, Dong Gil,Roh, Sang Weon,Lee, Chulbom
supporting information, p. 9273 - 9276 (2014/08/05)
The C-H imidation of arenes and heteroarenes has been achieved via visible light induced photocatalysis. In the presence of an iridium(iii) photoredox catalyst, the reaction of aromatic substrates with N-chlorophthalimide furnishes the N-aryl products at room temperature through a nitrogen-centered radical mediated aromatic substitution.
Synthesis of some biologically active 2,6-dichloro-1-(N-substituted phenyl)-1,4-dihydropyridine-3,5-Dicarbaldehydes using vilsmeier-haack reaction and their applications
Rajput,Girase
, p. 201 - 208 (2013/09/24)
Various 2,6-dichloro-1-(N-substituted phenyl)-1,4-dihydropyridine-3,5- dicarbaldehydes were synthesized in two steps using moderate conditions and 3,5-diformyl groups were transformed into different functionalities. The synthesized compounds were screened
Intermolecular oxidative C-N bond formation under metal-free conditions: Control of chemoselectivity between aryl sp2 and benzylic sp 3 C-H bond imidation
Kim, Hyun Jin,Kim, Jiyu,Cho, Seung Hwan,Chang, Sukbok
supporting information; experimental part, p. 16382 - 16385 (2011/12/13)
A new synthetic approach toward intermolecular oxidative C-N bond formation of arenes has been developed under transition-metal-free conditions. Complete control of chemoselectivity between aryl sp2 and benzylic sp 3 C-H bond imidation was achieved by the choice of nitrogen sources, representatively being phthalimide and dibenzenesulfonimide, respectively.
Chemoselective hydrogenation of imides catalyzed by Cp*Ru(PN) complexes and its application to the asymmetric synthesis of paroxetine
Ito, Masato,Sakaguchi, Ayaka,Kobayashi, Chika,Ikariya, Takao
, p. 290 - 291 (2008/04/18)
This work represents the first catalytic hydrogenation of imides into amides and primary alcohols, in which the unique chemoselectivity is originated from the bifunctional nature of ruthenium-NH moiety in the catalyst. Copyright
Concise and short synthesis of functionalized 5,6-dihydropyridin-2-ones by means of palladium(0)-catalyzed cross-coupling of ketene aminal phosphates
Fuwa, Haruhiko,Kaneko, Akane,Sugimoto, Yasuaki,Tomita, Taisuke,Iwatsubo, Takeshi,Sasaki, Makoto
, p. 101 - 106 (2007/10/03)
A concise and short synthetic entry to 5,6-dihydropyridin-2-one derivatives has been developed by means of palladium(0)-catalyzed cross-coupling of cyclic ketene aminal phosphates.
Antinociceptive properties of N-aryl-glutaramic acids and N-aryl-glutarimides
Stiz,Souza,Golin,Neto,Correa,Nunes,Yunes,Cechinel-Filho
, p. 942 - 944 (2007/10/03)
This study describes the antinociceptive activity of some N-aryl-glutaramic acids and N-aryl-glutarimides in writhing and formalin tests, two classical models of pain in mice. These compounds show high activity, being more active than acetyl salycilic aci
N-CYANOIMIDES: REACTIVITY WITH AMINE NUCLEOPHILES
Stephens, Randall W.,Domeier, Linda A.,Todd, Michael G.,Nelson, Veronica A.
, p. 733 - 736 (2007/10/02)
N-Cyanoimides are useful precursors to N-alkyl or N-aryl imides.Treatment of aromatic N-cyanoimides such as N-cyanophthalimide (1) with primary amines provides N-substituted imides directly, while aliphatic N-cyanoimides afford diamide intermediates which can be converted to N-substituted imides upon heating.
REACTIVITY OF IMINOPHOSPHORANES TOWARDS SOME SYMMETRICAL DICARBONYL DICHLORIDES : SYNTHESES AND MECHANISMS
Aubert, Thierry,Farnier, Michel,Guilard, Roger
, p. 53 - 60 (2007/10/02)
In situ generated iminophosphoranes 1 react with dicarbonyl dihalides 2a-b and 3a-c to give known or new nitrogen heterocycles.The proposed mechanisms involve elimination of either triphenyl-phosphine oxide or dichlorotriphenylphosphorane depending upon both the iminophosphorane and the dicarbonyl compound.
