908129-34-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 908129-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,8,1,2 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 908129-34:
(8*9)+(7*0)+(6*8)+(5*1)+(4*2)+(3*9)+(2*3)+(1*4)=170
170 % 10 = 0
So 908129-34-0 is a valid CAS Registry Number.

Palladium-catalyzed trifluoroacetate-promoted mono-arylation of the β-methyl group of alanine at room temperature: Synthesis of β-arylated α-amino acids through sequential C-H functionalization

Wang, Bo,Nack, William A.,He, Gang,Zhang, Shu-Yu,Chen, Gong

, p. 3952 - 3957 (2014)

We report a highly efficient and practical protocol for palladium-catalyzed N-quinolylcarboxamide (AQ)-directed arylation of the unactivated β-C(sp3)-H bonds of alanine with aryl iodides at room temperature. For the first time, a broad range of easily accessible aryl iodides can be installed onto the β-methyl group of AQ-coupled phthaloyl alanine mono-selectively, providing both natural and unnatural aromatic α-amino acids. Access to these mono-arylated compounds enables subsequent AQ-directed diastereoselective C-H functionalization, allowing the preparation of various β-disubstituted aromatic α-amino acids in a programmable manner.

Sulfonamide-promoted palladium(II)-catalyzed alkylation of unactivated methylene C(sp3)-H bonds with alkyl iodides

Chen, Kai,Shi, Bing-Feng

, p. 11950 - 11954 (2014)

The alkylation of unactivated b-methylene C(sp3)-H bonds of a-amino acid substrates with a broad range of alkyl iodides using Pd(OAc)2 as the catalyst is described. The addition of NaOCN and 4-Cl-C6H4SO2/s

Divergent and Stereoselective Synthesis of β-Silyl-α-Amino Acids through Palladium-Catalyzed Intermolecular Silylation of Unactivated Primary and Secondary C?H Bonds

Liu, Yue-Jin,Liu, Yan-Hua,Zhang, Zhuo-Zhuo,Yan, Sheng-Yi,Chen, Kai,Shi, Bing-Feng

supporting information, p. 13859 - 13862 (2016/10/26)

A general and practical PdII-catalyzed intermolecular silylation of primary and secondary C?H bonds of α-amino acids and simple aliphatic acids is reported. This method provides divergent and stereoselective access to a variety of optical pure
