Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 5451-40-1, is researched, Molecular C5H2Cl2N4, about 1,2,3-Triazoles as leaving groups in SNAr-arbuzov reactions: synthesis of C6-phosphonated purine derivatives, the main research direction is heptyl bisphenyltriazolyl purine regioselective nucleophilic aromatic substitution Arbuzov reaction; diethoxyphosphoryl heptyl triazolyl purine preparation; 2,6-bistriazolylpurines; Arbuzov reaction; nucleophilic aromatic substitution; purinylphosphonates.Formula: C5H2Cl2N4.
A new method for C-N bond transformations into C-P bonds was developed using 1,2,3-triazoles as leaving groups in SNAr-Arbuzov reactions. A series of C6-phosphonated 2-triazolylpurine derivatives I [R = methoxycarbnonyl, Bu, 2-pyridyl, etc.] was synthesized for the first time, with the isolated yields reaching up to 82% in the C-P-bond-forming event. The SNAr-Arbuzov reaction of 2,6-bistriazolylpurines follows the general regioselectivity pattern of the C6-position being more reactive towards substitution, which was unambiguously proved by X-ray anal. of I [R = phenyl].
