Phenylalanine and N-acetylphenylalanyl are two distinct chemical compounds. Phenylalanine is an essential amino acid, which means it cannot be synthesized by the human body and must be obtained through diet. It plays a crucial role in various physiological processes, including the production of neurotransmitters like dopamine and norepinephrine, and the synthesis of melanin, a pigment responsible for skin, hair, and eye color. N-acetylphenylalanyl, on the other hand, is a modified form of phenylalanine where an acetyl group is attached to the nitrogen atom. This modification can alter the chemical properties and potential applications of the compound, such as in the development of pharmaceuticals or as a building block in peptide synthesis. Both compounds are significant in the field of biochemistry and have implications for health and medicine.

4221-07-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4221-07-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4221-07:
(6*4)+(5*2)+(4*2)+(3*1)+(2*0)+(1*7)=52
52 % 10 = 2
So 4221-07-2 is a valid CAS Registry Number.

Efficient 1,4-Asymetric Induction Utilizing Electrostatic Interaction between Ligand and Substrate in the Asymmetric Hydrogenation of Didehydrodipeptides

Yamagishi, Takamichi,Ikeda, Satoru,Yatagai, Masanobu,Yamaguchi, Motowo,Hida, Mitsuhiko

, p. 1787 - 1790 (2007/10/02)

Electrostatic interaction between the amino group of the achiral 3-dimethylaminopropylidenebismethylenebis(diphenylphosphine) (1) and the carboxy group of the substrate enable an effective 1,4-asymmetric induction in the RhI-catalysed hydrogenation of didehydrodipeptides, to give (S,S)-or (R,R)-products selectively.The selectivity reached up to 94percent diastereoisomeric excess with acetyl didehydrodipeptides and 92percent with benzyloxycarbonyl substrates.

EFFECTIVE ASYMMETRIC HYDROGENATION OF DEHYDRODIPEPTIDES WITH RHODIUM(I)-NEW CHIRAL DIPHOSPHINITE SYSTEMS

Yatagai, Masanobu,Zama, Masanobu,Yamagishi, Takamichi,Hida, Mitsuhiko

, p. 1203 - 1206 (2007/10/02)

Rh(I)-new chiral diphosphinite systems with terminal amino groups were very effective for asymmetric hydrogenation of dehydrodipeptides with free carboxyl group and a chiral carbon.The effectiveness of the diphosphinite catalysts strongly suggests the contribution of electrostatic effect to asymmetric induction.
