Synthesis of Adenosine 5'- (Aminoalkyl phosphonates and phosphinates) Analogues of Aminoacyl Adenylates
Translation of the genetic code and protein synthesis from amino acids takes place in the ribosome’s where tRNAs act as key intermediates. Correct translation of genetic information into the specific amino acids is dependent on aminoacyl-tRNA ́s. The synthesis of these is catalyzed by aminoacyl-tRNA synthetase. The aminoacylation reaction, the so-called charging of tRNA is carried out in two ste...
متن کاملDirect phosphonation of quinoxalin-2(1H)-ones under transition-metal-free conditions.
A direct C-H bond phosphonation of quinoxalin-2(1H)-ones with H-phosphonates, H-phosphinates or H-phosphine oxides has been developed. A wide variety of heteroaryl phosphonates were obtained in up to 92% yield for 20 examples under transition-metal-free conditions. This protocol tolerates a broad scope of substrates and features practicality, high efficiency, environmental friendliness and atom...
متن کاملTailoring the photoluminescence properties of transition metal phosphonates.
A series of phenylphosphonates, Zn(1-x)Mn(x)(O(3)PC(6)H(5)) x H(2)O, where x = 0, 0.005, 0.25, 0.5, 0.75 and 1.0, has been prepared and their photoluminescence responses studied. The presence of Mn in the sample results in a red emission, whilst when x = 0 the emission is green. Levels of Mn <1 mol% result in an orange emission. Ag(6)(m-O(3)PC(6)H(4)CO(2))(2) has been prepared by hydrothermal r...
متن کاملSyntheses, crystal structures, thermal stabilities, luminescence and magnetism of two 3D pillared metal phosphonates.
Two pillared metal phosphonates: [Mn3(4,4'-bipy)(L)2].(4,4'-bipy)0.5 (1) and [Co3(4,4'-bipy)(H2O)2(L)2].(4,4'-bipy)0.5 (2) (L = O3PCH(OH)CO2), have been synthesized hydrothermally, and characterized by single-crystal X-ray diffraction along with powder XRD, EA, IR and TGA. In compounds 1-2, Mn(II) and Co(II) ions are in octahedron coordination geometries and bridged by 2-hydroxyl(phosphono)acet...
متن کاملMonoorganoantimony(v) phosphonates and phosphoselininates.
Molecular oxo-hydroxo clusters have been synthesized by reactions of arylstibonic acids with organophosphonic acid and phenylseleninic acid. Single crystal X-ray structural elucidation revealed the formation of [(p-i-PrC6H4Sb)4(OH)4(t-BuPO3)6] (1), [(p-t-BuC6H4Sb)4(O)2(PhPO3)4(PhPO3H)4] (2), [(p-i-PrC6H4Sb)4(O)3(OH)(PhSeO2)2(t-BuPO3)4(t-BuPO3H2)2] (3), [(p-MeC6H4Sb)4(O)3(OH)(PhSeO2)2(t-BuPO3)4(...
