107554-38-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107554-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,5,5 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 107554-38:
(8*1)+(7*0)+(6*7)+(5*5)+(4*5)+(3*4)+(2*3)+(1*8)=121
121 % 10 = 1
So 107554-38-1 is a valid CAS Registry Number.

Catalytic asymmetric 1,3-dipolar cycloaddition of α-iminonitriles

Robles-Machín, Rocío,Alonso, Inés,Adrio, Javier,Carretero, Juan C.

supporting information; experimental part, p. 5286 - 5291 (2010/10/01)

(Figure Presented) Improving the structural scope: A catalytic asymmetric 1,3-dipolar cycloaddition involving α-iminonitriles as azomethine precursors has been developed. In the presence of AgOAc/ Taniaphos as the catalyst system the reaction of α-iminonitriles with dimethyl fumarate and N-methyl maleimide affords 2-cyanopyrrolidines with good endo selectivity and enantioselectivity (68-≥99% ee; see scheme).

, (2008/06/13)

The invention relates to a process for preparing α-amino acid amides, the corresponding α-amino acids, or salt thereof, which are substituted at the β-site with at least one (hetero)aromatic group. This is achieved according to the invention by subjecting

Stereoselectivity of Cycloaddition of N-(Cyanomethyl)- and N-(α-Cyanobenzyl)imines with Olefinic Dipolarophiles. Synthetic Equivalents of Nitrile Ylide 1,3-Dipoles

Tsuge, Otohiko,Ueno, Kazunori,Kanemasa, Shuji,Yorozu, Kiyotaka

, p. 1809 - 1824 (2007/10/02)

N-(Cyanomethyl)- and N-(α-cyanobenzyl)imines derived from a variety of aldehydes and ketones can tautomerize into N-protonated azomethine ylides which undergo cycloadditions with olefinic dipolarophiles.These cycloadditions are often accompanied by the el
