1. Bis(cyclohexylammonium) 2,2'-disulfanediyldibenzoate
Xinting Wei, Jing Li, Handong Yin Acta Crystallogr Sect E Struct Rep Online. 2011 Jan 12;67(Pt 2):o319. doi: 10.1107/S1600536810054012.
In the title molecular salt, 2C(6)H(14)N(+)·C(14)H(8)O(4)S(2) (2-), the complete dianion is generated by crystallographic twofold symmetry and a twisted conformation is found [the C-S-S-C torsion angle is 87.13 (2)° and the dihedral angle between the rings is 83.4 (2)°]. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the cations and anions.
2. Bis(cyclo-hexyl-ammonium) tetra-bromido-cuprate(II)
Meng Ting Han Acta Crystallogr Sect E Struct Rep Online. 2012 Apr 1;68(Pt 4):m448. doi: 10.1107/S1600536812011117. Epub 2012 Mar 21.
The structure of the title salt, (C(6)H(14)N)(2)[CuBr(4)], is built up from cyclo-hexyl-ammonium cations and tetra-bromidocuprate anions, the latter being located on an inversion center. In the crystal, anions and cations are inter-connected by N-H⋯Br hydrogen bonds, forming ribbons parallel to [0-11].
3. Synthesis of α-D-Ribose 1-Phosphate and 2-Deoxy-α-D-Ribose 1-Phosphate Via Enzymatic Phosphorolysis of 7-Methylguanosine and 7-Methyldeoxyguanosine
Irina V Varizhuk, Vladimir E Oslovsky, Pavel N Solyev, Mikhail S Drenichev, Sergey N Mikhailov Curr Protoc. 2022 Jan;2(1):e347. doi: 10.1002/cpz1.347.
A simple and efficient method for the preparation of α-D-ribose 1-phosphate and 2-deoxy-α-D-ribose 1-phosphate, key intermediates in nucleoside metabolism and important starting compounds for the enzymatic synthesis of various modified nucleosides, has been proposed. It consists in near-irreversible enzymatic phosphorolysis of readily prepared hydroiodide salts of 7-methylguanosine and 7-methyl-2'-deoxyguanosine, respectively, in the presence of purine nucleoside phosphorylase. α-D-Ribose 1-phosphate and 2-deoxy-α-D-ribose 1-phosphate are obtained in near quantitative yields (by HPLC analysis) and 74%-94% yields after their isolation and purification. © 2022 Wiley Periodicals LLC.
