N,N'-bis-((S)-1-phenyl-ethyl)-fumaramide, also known as (S)-N-(1-phenylethyl)-N'-(1-phenylethyl)-fumaramide, is a chiral compound with a molecular formula of C22H22N2O4. It is a derivative of fumaramide, which is a dicarboximide with two carbonyl groups. The compound features two (S)-1-phenylethyl groups attached to the nitrogen atoms of the fumaramide core, giving it a symmetrical structure. This chemical is often used as a ligand in coordination chemistry, particularly in the formation of metal complexes, due to its ability to chelate metal ions through its nitrogen atoms. It is also of interest in the field of asymmetric synthesis, where it can be used to create chiral catalysts or as a building block for more complex chiral molecules. The specific properties and applications of N,N'-bis-((S)-1-phenyl-ethyl)-fumaramide can vary depending on the context in which it is used, but its unique structure makes it a valuable tool in the synthesis of various organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 7683-78-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7683-78:
(6*7)+(5*6)+(4*8)+(3*3)+(2*7)+(1*8)=135
135 % 10 = 5
So 7683-78-5 is a valid CAS Registry Number.

Efficient synthesis of fumaric amides through cross-metathesis of acrylic amides with the NHC Grubbs ruthenium catalyst

Streuff, Jan,Mu?iz, Kilian

, p. 5973 - 5978 (2005)

Application of the second generation Grubbs metathesis catalyst for the homo-cross-metathesis of acroyl amides from chiral amines is reported. This efficient and high-yielding reaction provides a side-product free synthesis of fumaric acid diamides which

First asymmetric aminohydroxylation of acrylamides

Streuff, Jan,Osterath, Brigitte,Nieger, Martin,Muniz, Kilian

, p. 3492 - 3496 (2007/10/03)

The first examples of the asymmetric aminohydroxylation of acryl amides are reported. This was accomplished with chiral acrylamides as substrates, which undergo diastereoselective oxidative transformation within the so-called 'second catalytic cycle' with diastereomeric excesses reaching 100:0. The reaction relies solely on the stereochemical information provided by the enantiomerically pure starting materials. A stereochemical model for the observed asymmetric induction is provided.
