The invention relates to the field of chemical synthesis, in particular to a hexahydro-5H-benzo [d] imidazole-5-ketone derivative and a preparation method and application thereof. According to the invention, 1, 3, 5-triazinane and quinonamine are used for
Facile Access to 3-Unsubstituted Tetrahydroisoquinolonic Acids via the Castagnoli-Cushman Reaction

, p. 2001 - 2008 (2018/03/06)
Hitherto undescribed 3-unsubstituted tetrahydroisoquinolonic acids (isolated as their respective methyl esters) were accessed for the first time by the uncatalyzed, thermally promoted Castagnoli-Cushman reaction (CCR) of homophthalic anhydride (HPA) and a series of 1,3,5-triazinanes. The moderate yields observed in some cases are most likely associated with a persistent impurity also formed in these reactions. The new scaffold is expected to find novel medicinal utility (compared to the traditional CCR adducts) because it lacks a substituent at the 3-position.
A facile and efficient ultrasound-assisted synthesis of 1,3,5-tris-arylhexahydro-1,3,5-triazine through mannich reaction

In this paper, we report a facile and efficient method for the synthesis of 1,3,5-tris-arylhexahydro-1,3,5-triazines by reaction of formaldehyde and aromatic amines catalyzed by triethylamine (Et3N) and assisted by ultrasound at rt. This method has the advantages of short reaction times, good.
Novel oxidative nitrogen to carbon rearrangement found in the conversion of anilines to benzaldoximes by treating with HCHO/H2O2

Novel rearrangement was found by reacting anilines with HCHO/H2O2 resulting in the synthesis of various benzaldoximes. The mechanism of the rearrangement is proposed and suggested that the rearrangement might proceed via unstable N-phenyloxazirane intermediate followed by the transfer of aryl moiety from nitrogen to carbon atom leading to the formation of benzaldoxime.
Preparation of N,O-Aminals as Synthetic Equivalents of H2C=NAr and (H2C=NHAr)+ ions: Neutral- and Acid-promoted Transformations

A general method for the synthesis of N, O-aminals derived from primary aromatic amines is described.The reactivity of these compounds under neutral and acidic conditions has been studied and the title compounds can be envisaged as general purpose H2C=NAr or (H2C=NAr)+ equivalents.N,O-Aminals have been converted into perhydrotriazines by moderate heating and into bis(4-aminoaryl)methane derivatives or N-benzylarylamines, respectively, when heated in acidid media with pH control.Reduction od N,O-acetals with sodium cyanoborohydride has revealed that the C-O bond is broken exclusively in acidic media.
