32119-53-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 32119-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,1,1 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 32119-53:
(7*3)+(6*2)+(5*1)+(4*1)+(3*9)+(2*5)+(1*3)=82
82 % 10 = 2
So 32119-53-2 is a valid CAS Registry Number.

Stevens rearrangement of anilinium salts by the action sodium carbonate hexahydrate

Shakhbazyan,Babakhanyan,Grigoryan,Kocharyan

, p. 1608 - 1610 (2003)

Anilinium salts containing an allyl-like group together with various functionally substituted receiving groups undergo Stevens rearrangement by the action of sodium carbonate hexahydrate in the absence of a solvent. As a result, both N-methylaniline deriv

Iron-catalyzed reductive strecker reaction

Yan, Fachao,Huang, Zijun,Du, Chen-Xia,Bai, Jian-Fei,Li, Yuehui

, p. 188 - 194 (2021/02/03)

Strecker reaction is widely applied for the synthesis of amino acids from aldehydes, amines and cyanides. Herein, we report the FeI2-catalyzed reductive Strecker type reaction of formamides instead of aldehydes to produce amino acetonitriles. The challenging capture of carbinolamine intermediates by CN? was achieved via Fe catalysis. This approach afforded better yields than the use of Ir- or Rh-catalysts. The application ability of this methodology is demonstrated by 1) one-pot construction of (13C labeled) complex molecules from CO2 via amino acetonitrile intermediates and 2) convenient production of homologated carboxylic acids from aldehydes.

Solvent-Free Synthesis of α-Amino Ketones from α-Hydroxyl Ketones via A Novel Tandem Reaction Sequence Based on Heyns Rearrangement

Li, Ling-Yu,Zeng, Qing-Le,Li, Guang-Xun,Tang, Zhuo

supporting information, p. 694 - 699 (2019/03/26)

Heyns rearrangement have been famous for carbohydrate chemists for several decades. However, this reaction was underrated as a useful method for synthetic chemists due to preparative shortcomings. Herein we developed an efficient method for the synthesis of pharmaceutically important α-amino ketones from readily available α-hydroxy ketones and secondary amines through a tandem reaction sequence based on Heyns rearrangement. The reaction smoothly proceeded by using catalytic PTSA as catalyst without solvent. Primary and secondary α-hydroxy ketones were readily used and regioselectively afforded the correspondingly α-amino ketones with moderate yield.
