70288-60-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70288-60-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,8 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70288-60:
(7*7)+(6*0)+(5*2)+(4*8)+(3*8)+(2*6)+(1*0)=127
127 % 10 = 7
So 70288-60-7 is a valid CAS Registry Number.

Deacetylation of α-bromo-α-substituted-acetoacetates

Hu, Youhong,Bai, Donglu

, p. 2375 - 2376 (1998)

A new and efficient method for the deacetylation of α-bromo-α- substituted-acetoacetates to obtain α-bromoesters has been achieved by treatment with LiClO4/Et3N in ether at room temperature.

Diastereo- And Enantioselective Synthesis of Quaternary α-Amino Acid Precursors by Copper-Catalyzed Propargylation

Zhu, Qiongqiong,Meng, Beibei,Gu, Congzheng,Xu, Ye,Chen, Jie,Lei, Chuanhu,Wu, Xiaoyu

supporting information, p. 9985 - 9989 (2019/12/24)

A diastereo- and enantioselective propargylic substitution reaction between propargylic carbonates and α-substituted nitroacetates catalyzed by a Cu-pybox complex is described. This method allows the preparation of a series of non-proteinogenic quaternary α-amino acid precursors featuring two contiguous stereogenic centers and a terminal alkyne moiety in high yields with good to excellent diastereo- and enantioselectivities in most cases. The propargylated adducts were elaborated into a diverse set of quaternary α-amino acid derivatives.
