Direct reductive coupling of secondary amides: chemoselective formation of vicinal diamines and vicinal amino alcohols.
We report the first one-pot reductive homocoupling reaction of secondary amides and cross-coupling reaction of secondary amides with ketones to give secondary vicinal diamines and amino alcohols. This method relies on the direct generation of α-amino carbon radicals from secondary amides by activation with trifluoromethanesulfonic anhydride, partial reduction with triethylsilane and samarium di...
متن کاملReaction of benzoylpyruvate with a mixture of aromatic aldehydes and 5-amino-1,3,4-thiadizole-2-thiol
Reactions of benzoylpyruvate with a mixture of aromatic aldehydes and 5-amino-1,3,4-thiadizole-2-thiol in a 1:1:1 molar ratio, afforded 5-(5-aryl-4-benzoyl-3-hydroxy-2-oxo-2,5-dihydro-1H-pyrrol-1-yl)-1,3,4-thiadizole-2-thiols (3a-c). The structure of the resulted products was confirmed by determination of the melting point and spectrophotometric techniques such as IR and 1H-NMR spectroscopy.
متن کاملCovalent Triazine Frameworks via a Low‐Temperature Polycondensation Approach
Covalent triazine frameworks (CTFs) are normally synthesized by ionothermal methods. The harsh synthetic conditions and associated limited structural diversity do not benefit for further development and practical large-scale synthesis of CTFs. Herein we report a new strategy to construct CTFs (CTF-HUSTs) via a polycondensation approach, which allows the synthesis of CTFs under mild conditions f...
متن کامل2,4-Dichloro-6-({2-[(3,5-dichloro-2-hydroxybenzylidene)amino]ethyl}iminomethyl)phenol
The title mol-ecule, C(16)H(12)Cl(4)N(2)O(2), lies about an inversion center. The symmetry-unique part of the mol-ecule contains an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules are arranged in corrugated layers parallel to (-101). Weak π-π stacking inter-actions, with a centroid-centroid diatance of 3.7923 (13) Å, are present.
متن کامل4,6-Dichloro-2-{[(E)-(3-{[(E)-3,5-dichloro-2-hydroxybenzylidene]amino}-2,2-dimethylpropyl)imino]methyl}phenol
In the title compound, C(19)H(18)Cl(4)N(2)O(2), a potential tetra-dentate Schiff base ligand, the dihedral angle between the two benzene rings is 48.01 (10)°. The configuration about the two C=N bonds is E and two intra-molecular O-H⋯N hydrogen bonds make S(6) ring motifs. In the crystal, mol-ecules are linked along the b axis via inter-molecular C-H⋯Cl inter-actions. The crystal structure is f...
