101693-40-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 101693-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,6,9 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 101693-40:
(8*1)+(7*0)+(6*1)+(5*6)+(4*9)+(3*3)+(2*4)+(1*0)=97
97 % 10 = 7
So 101693-40-7 is a valid CAS Registry Number.

CsF in organic synthesis. The first and convenient synthesis of enantiopure bisoprolol by use of glycidyl nosylate

Kitaori, Kazuhiro,Furukawa, Yoshiro,Yoshimoto, Hiroshi,Otera, Junzo

, p. 3173 - 3176 (1998)

The regioselective substitution of glycidyl nosylate with phenols is catalyzed by CsF in the presence of K2CO3 in DMF; this reaction enables the first and convenient synthesis of enantiopure bisoprolol.

Improving the activity and enantioselectivity of PvEH1, a Phaseolus vulgaris epoxide hydrolase, for o-methylphenyl glycidyl ether by multiple site-directed mutagenesis on the basis of rational design

Li, Chuang,Kan, Ting-Ting,Hu, Die,Wang, Ting-Ting,Su, Yong-Jun,Zhang, Chen,Cheng, Jian-Qing,Wu, Min-Chen

, (2019/08/01)

Substrate spectrum assay exhibited that PvEH1, which is an epoxide hydrolase from P. vulgaris, had the highest specific activity and enantiomeric ratio (E) for racemic o-methylphenyl glycidyl ether (rac-1) among tested aryl glycidyl ethers (1–5). To produce (R)-1 via kinetic resolution of rac-1 efficiently, the catalytic properties of PvEH1 were further improved on the basis of rational design. Firstly, the seven single-site variants of PvEH1-encoding gene (pveh1) were PCR-amplified as designed, and expressed in E. coli BL21(DE3). Among all expressed single-site mutants, PvEH1L105I and PvEH1V106I had the highest specific activities of 17.6 and 16.4 U/mg protein, respectively, while PvEH1L196D had an enhanced E value of 9.2. Secondly, to combine their respective merits, one triple-site variant, pveh1L105I/V106I/L196D, was also amplified, and expressed. The specific activity, E value, and catalytic efficiency of PvEH1L105I/V106I/L196D were 23.1 U/mg, 10.9, and 6.65 mM?1 s?1, respectively, which were 2.0-, 1.8- and 2.4-fold higher than those of wild-type PvEH1. The source of PvEH1L105I/V106I/L196D with enhanced E value for rac-1 was preliminarily analyzed by molecular docking simulation. Finally, the scale-up kinetic resolution of 100 mM rac-1 was conducted using 5 mg wet cells/mL E. coli/pveh1L105I/V106I/L196D at 25 °C for 1.5 h, producing (R)-1 with 95.0% ees, 32.1% yield and 3.52 g/L/h space-time yield.

Chiral nanoporous metal-metallosalen frameworks for hydrolytic kinetic resolution of epoxides

Zhu, Chengfeng,Yuan, Guozan,Chen, Xu,Yang, Zhiwei,Cui, Yong

supporting information; experimental part, p. 8058 - 8061 (2012/07/14)

Chiral nanoporous metal-organic frameworks are constructed by using dicarboxyl-functionalized chiral Ni(salen) and Co(salen) ligands. The Co(salen)-based framework is shown to be an efficient and recyclable heterogeneous catalyst for hydrolytic kinetic resolution (HKR) of racemic epoxides with up to 99.5% ee. The MOF structure brings Co(salen) units into a highly dense arrangement and close proximity that enhances bimetallic cooperative interactions, leading to improved catalytic activity and enantioselectivity in HKR compared with its homogeneous analogues, especially at low catalyst/substrate ratios.
