A mild and effective one-pot synthesis of 1,2,3-benzotriazin-4(3H)-ones and benzothiatriazine-1,1(2H)-dioxide analogues has been developed. The method involves the diazotisation and subsequent cyclisation of 2-aminobenzamides and 2-aminobenzenesulfonamides via stable diazonium salts, prepared using a polymer-supported nitrite reagent and p-tosic acid. The transformation was compatible with a wide range
开发了一种温和有效的一锅法合成 1,2,3-benzotriazin-4(3 H )-ones 和 benzothiatriazine-1,1( 2H )-dioxide 类似物。该方法涉及通过使用聚合物负载的亚硝酸盐试剂和对甲苯磺酸制备的稳定的重氮盐对 2-氨基苯甲酰胺和 2-氨基苯磺酰胺进行重氮化和随后的环化。该转化与多种芳基官能团和酰胺/磺酰胺取代基相容,可用于合成药学上重要的靶标。通过制备含有 1,2,3-benzotriazin-4(3 H )-one的 α-氨基酸,进一步证明了一锅重氮环化过程的合成效用。

Provided are substituted benzaldehydes and derivatives thereof that act as allosteric modulators of hemoglobin, methods and intermediates for their preparation, pharmaceutical compositions comprising the modulators, and methods for their use in treating disorders mediate by hemoglobin and disorders that would benefit from increased tissue oxygenation.
1,2,3-Benzotriazin-4(3H)-ones react with 1,3-dienes in the presence of a nickel(0)/phosphine complex to give a variety of 3,4-dihydroisoquinolin-1(2H)-ones. Oxidative insertion of nickel(0) into the triazinone moiety prompts extrusion of dinitrogen to give a five-membered ring azanickelacyclic intermediate. Subsequent insertion of 1,3-dienes into the nickel−carbon bond followed by allylic amidation
The title compound is prepared by methylation of 1,2,3-benzotriazin-4(3H)-one, protected at the 3-position by a 1-ethoxyethyl substituent, followed by removal of the protective group; the unusual physicochemical properties of the compound are probably associated with a highly polar structure.
