Aldoses exist predominantly in the cyclic hemiacetal form, which is in equilibrium with the open-chain aldehyde form. The small aldehyde content hampers reactivity when chemistry addresses the carbonyl moiety. This low concentration of the available aldeh
1,2-Dihydro-4-quinazolinamines: Potent, highly selective inhibitors of inducible nitric oxide synthase which show antiinflammatory activity in vivo
Tinker, Alan C.,Beaton, Haydn G.,Boughton-Smith, Nigel,Cook, Tony R.,Cooper, Sally L.,Fraser-Rae, Lynne,Hallam, Kay,Hamley, Peter,McInally, Tom,Nicholls, David J.,Pimm, Austen D.,Wallace, Alan V.

Imidazole hydrochloride as an additive promotes the reaction of amidoximes and DMA derivatives to generated 3,5-disubstituted-1,2,4-oxadiazoles in low to excellent yields without the use of coupling reagents, oxidants, strong acids or bases and other additives.
Substrate-Independent High-Throughput Assay for the Quantification of Aldehydes
Ressmann, Anna K.,Schwendenwein, Daniel,Leonhartsberger, Simon,Mihovilovic, Marko D.,Bornscheuer, Uwe T.,Winkler, Margit,Rudroff, Florian

The selective and direct reduction of carboxylic acids into the corresponding aldehydes by chemical methods is still a challenging task in synthesis. Several reductive and oxidative chemical methods are known to produce aldehydes, but most of them require
Practical synthesis of N -substituted cyanamides via tiemann rearrangement of amidoximes

A facile and general synthesis of various N-substituted cyanamides was accomplished by the Tiemann rearrangement of amidoximes with benzenesulfonyl chlorides (TsCl or o-NsCl) and DIPEA.
Synthetic studies toward 3-(acylamino)-1 H-indazoles and development of a one-pot, microwave-assisted, oxadiazole condensation/Boulton-Katritzky rearrangement
Ott, Gregory R.,Anzalone, Andrew V.
supporting information; experimental part, p. 3018 - 3022 (2012/01/05)
Studies on the Boulton-Katritzky rearrangement of 3-(2-aminoaryl)-1,2,4- oxadiazoles have led to the identification of additional electronic factors that govern the rearrangement as well as a competitive thermal rearrangement pathway for select substrates

Compounds of the general formula: (I) wherein Y, R and R’ are as described in the specification. Further included are pharmaceutical compositions comprising the compounds, processes for their preparation, as well as the use of the compounds for the prepar
A New type of Dimroth Rearrangement: Formation of 1,2-Dihydro-3H-quinazolone 4-Oximes from 4-Amino-1,2-dihydroquinazoline 3-Oxides

, p. 2163 - 2168 (2007/10/02)
Contrary to earlier claims the primary product of the reaction of aldehydes and o-aminobenzamide oxime is, irrespective of the aldehyde, always a 4-amino-1,2-dihydroquinazoline 3-oxide.Thermolysis of 1-unsubstituted 2-substituted quinazoline 3-oxides (5) in solution or in melt gives rise, by a new type of Dimroth rearrangement, to the isomeric 1,2-dihydro-4-quinazolone oximes (6), while the 1-benzyl 2-unsubstituted analogue (9j) yields, presumably by an addition-elimination ring transformation coupled with oxidation, a quinoidal quinazolone 4-oxime (17).
