518038-34-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 518038-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,8,0,3 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 518038-34:
(8*5)+(7*1)+(6*8)+(5*0)+(4*3)+(3*8)+(2*3)+(1*4)=141
141 % 10 = 1
So 518038-34-1 is a valid CAS Registry Number.

Easily accessible and highly tunable bisphosphine ligands for asymmetric hydroformylation of terminal and internal alkenes

Xu, Kun,Zheng, Xin,Wang, Zhiyong,Zhang, Xumu

, p. 4357 - 4362 (2014/05/06)

An efficient methodology for synthesizing a small library of easily tunable and sterically bulky ligands for asymmetric hydroformylation (AHF) has been reported. Five groups of alkene substrates have been tested with excellent conversions, moderate-to-excellent regio- and enantioselectivities. Among the best result of the reported literature, application of ligand 1 c in the highly selective AHF of the challenging substrate 2,5-dihydrofuran yielded almost one isomer in up to 99 % conversion along with enantiomeric excesses (ee) of up to 92 %. Highly enantioselective AHF of dihydropyrrole substrates is achieved using the same ligand, with up to 95 % ee and up to >1:50 β-isomer/α- isomer ratio. The simpler the better! An efficient method for the easy and tunable synthesis of a series of asymmetric hydroformylation (AHF) ligands from low-cost, commercially available starting materials has been reported. These ligands can give excellent conversions and moderate to excellent regio- and enantioselectivities for a broad range of mono- and disubstituted alkenes with a low catalyst loading (substrate-to-catalyst ratios (S/C) of 1000:1 to 3000:1).

, p. 1903 - 1907 (2008/02/04)

Following the discovery of N-acyl-1,4-diazepan-2-one as a novel pharmacophore for potent and selective DPP-4 inhibitors, optimization of this new lead with different substitution on the seven-membered ring resulted in several highly potent and selective,

Highly enantioselective conjugate addition of dialkylzinc reagents to acyclic nitroalkenes: A catalytic route to β2-amino acids, aldehydes, and alcohols

Duursma, Ate,Minnaard, Adriaan J.,Feringa, Ben L.

, p. 3700 - 3701 (2007/10/03)

Using chiral phosphoramidite ligand (S,R,R)-L1 in the conjugate addition to acyclic nitroalkenes for the first time, we obtained enantioselectivities up to 98%. The use of acyclic substrates with different dialkylzinc reagents provides a catalytic enantio
