Uses

N-Cbz-L-aspartic acid is an N-Cbz-protected form of L-Aspartic acid (A790024). L-Aspartic acid is a nonessential amino acid that is used to biosynthesize other amino acids within the human body. L-Aspartic acid also increases membrane conductance of mammalian neurons by voltage-dependent means, causing depolarization and nerve impulses that travel to key areas of the central nervous system.

Check Digit Verification of cas no

The CAS Registry Mumber 1152-61-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1152-61:
(6*1)+(5*1)+(4*5)+(3*2)+(2*6)+(1*1)=50
50 % 10 = 0
So 1152-61-0 is a valid CAS Registry Number.

On the racemisation of aspartic anhydride during its preparation

Buron, Frederic,Deguest, Geoffrey,Bischoff, Laurent,Fruit, Corinne,Marsais, Francis

, p. 1625 - 1627 (2007)

Due to the possible differentiation of both carboxyl groups, N-protected aspartic anhydride is a useful starting material in synthesis. However, most methods published in the literature for its formation lead to partial racemisation, which is generally not mentioned. Herein we report a comparison between the main methods published, with accurate measurements of the enantiomeric purity of this compound.

Regioselective opening of N-Cbz glutamic and aspartic anhydrides with carbon nucleophiles

Deguest, Geoffrey,Bischoff, Laurent,Fruit, Corinne,Marsais, Francis

, p. 2120 - 2125 (2006)

Depending on the experimental conditions, aspartic and glutamic anhydrides can be opened regioselectively with Grignard reagents, thus giving access to different isomers of chiral amino-ketoesters.

Environmentally Benign CO2-Based Copolymers: Degradable Polycarbonates Derived from Dihydroxybutyric Acid and Their Platinum-Polymer Conjugates

Tsai, Fu-Te,Wang, Yanyan,Darensbourg, Donald J.

supporting information, p. 4626 - 4633 (2016/05/19)

(S)-3,4-Dihydroxybutyric acid ((S)-3,4-DHBA), an endogenous straight chain fatty acid, is a normal human urinary metabolite and can be obtained as a valuable chiral biomass for synthesizing statin-class drugs. Hence, its epoxide derivatives should serve as promising monomers for producing biocompatible polymers via alternating copolymerization with carbon dioxide. In this report, we demonstrate the production of poly(tert-butyl 3,4-dihydroxybutanoate carbonate) from racemic-tert-butyl 3,4-epoxybutanoate (rac-tBu 3,4-EB) and CO2 using bifunctional cobalt(III) salen catalysts. The copolymer exhibited greater than 99% carbonate linkages, 100% head-to-tail regioselectivity, and a glass-transition temperature (Tg) of 37 °C. By way of comparison, the similarly derived polycarbonate from the sterically less congested monomer, methyl 3,4-epoxybutanoate, displayed 91.8% head-to-tail content and a lower Tg of 18 °C. The tert-butyl protecting group of the pendant carboxylate group was removed using trifluoroacetic acid to afford poly(3,4-dihydroxybutyric acid carbonate). Depolymerization of poly(tert-butyl 3,4-dihydroxybutanoate carbonate) in the presence of strong base results in a stepwise unzipping of the polymer chain to yield the corresponding cyclic carbonate. Furthermore, the full degradation of the acetyl-capped poly(potassium 3,4-dihydroxybutyrate carbonate) resulted in formation of the biomasses, β-hydroxy-γ-butyrolacetone and 3,4-dihydroxybutyrate, in water (pH = 8) at 37 °C. In addition, water-soluble platinum-polymer conjugates were synthesized with platinum loading of 21.3-29.5%, suggesting poly(3,4-dihydroxybutyric acid carbonate) and related derivatives may serve as platinum drug delivery carriers.
