7635-28-1 Usage
General Description
2-amino-3-(3-methoxy-phenyl)-propionic acid, also known as homophenylalanine, is a non-proteinogenic amino acid with a chemical structure containing an amino group, a carboxylic acid group, and a side chain consisting of a 3-methoxy-phenyl group. It is often used as a building block in the synthesis of peptides and proteins, and it has been investigated for its potential therapeutic applications in the fields of neuroscience and pharmaceuticals. Additionally, homophenylalanine has been studied for its role in inhibiting enzymes involved in the biosynthesis of neurotransmitters, making it a potential drug target for conditions related to neurotransmitter imbalances.
Check Digit Verification of cas no
The CAS Registry Mumber 7635-28-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7635-28:
(6*7)+(5*6)+(4*3)+(3*5)+(2*2)+(1*8)=111
111 % 10 = 1
So 7635-28-1 is a valid CAS Registry Number.

Alkylation of N′-[(S)-1′-phenylethyl]-N-(diphenylmethylene)glycinamide using a phase transfer catalyst (PTC) for practical asymmetric syntheses of α-amino acid derivatives

The chiral auxiliary mediated stereoselective alkylation reaction of N′-[(S)-1′-phenylethyl]-N-(diphenylmethylene)glycinamide (1) using a phase transfer catalyst (PTC) is described. Alkylation of 1 using 18-crown-6 as a PTC for liquid-solid extraction of KOH in toluene gives best results. This methodology provides a practical protocol for the preparation of a variety of enantio-enriched unnatural α-amino acid derivatives up to 83:17 enantiomeric ratio.
