197632-85-2 Usage

General Description

N-ME-ASP(OTBU)-OH refers to a specific type of chemical compound used primarily in scientific research or pharmaceuticals. The 'N-ME' refers to a Nitrogen molecule bonded to a Methyl group, 'ASP' represents the compound Aspartic acid, and the 'OTBU' symbolizes t-butoxycarbonyl, which is a protecting group commonly used in organic chemistry to prevent unwanted reactions. The 'OH' implies presence of a hydroxyl group. N-ME-ASP(OTBU)-OH might play a crucial role in the synthesis of certain proteins or in the development of certain drugs. Nevertheless, authoritative information regarding its exact use and properties is limited hence it is important for researchers to undertake further studies to understand more about this chemical compound.

Check Digit Verification of cas no

The CAS Registry Mumber 197632-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,6,3 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 197632-85:
(8*1)+(7*9)+(6*7)+(5*6)+(4*3)+(3*2)+(2*8)+(1*5)=182
182 % 10 = 2
So 197632-85-2 is a valid CAS Registry Number.

Synthesis method of N-methyl-(2S)-2-N-fluorenylmethoxycarbonylamino-aspartic acid (4-tert-butyl ester)

-

Paragraph 0010, (2020/06/16)

The invention relates to a synthesis method of N-methyl-(2S)-2-N-fluorenylmethoxycarbonyl amino-aspartic acid (4-tert-butyl ester). The method mainly solves the technical problem of product racemization and the problem of large-scale production in the existing synthesis method. The preparation method comprises the following four steps: step 1, dissolving a raw material A in tetrahydrofuran, addingcesium carbonate and methyl iodide to obtain a compound 1, and directly applying the product to the next step of reaction without purification; 2, at room temperature, introducing hydrogen into the compound 1 to react in methanol, and carrying out palladium-carbon catalysis to obtain a compound 2; 3, dissolving the compound 2 in methyl alcohol, adding L-(-)-diacetyl tartaric acid, and carrying out salifying treatment until ee is larger than 99%, so that a compound 3 is obtained, 4, performing a reaction on the compound 3 with acetone and sodium hydroxide, adding Fmoc-OSu is added for a reaction, and performing hydrochloric acid acidification to obtain the target compound 4.
