(2S,4R)-4-((tert-butoxycarbonyl)amino)-2-methyl-5-phenylpentanoic acid is a derivative of the natural amino acid leucine and is often used as a protecting group for the amine functional group. It is commonly used in organic chemistry and biochemistry research to help modify and control the reactivity of amino acids and peptides.

Check Digit Verification of cas no

The CAS Registry Mumber 368870-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,6,8,8,7 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 368870-65:
(8*3)+(7*6)+(6*8)+(5*8)+(4*7)+(3*0)+(2*6)+(1*5)=199
199 % 10 = 9
So 368870-65-9 is a valid CAS Registry Number.

Tubulysin Synthesis Featuring Stereoselective Catalysis and Highly Convergent Multicomponent Assembly

Vishwanatha, Thimmalapura M.,Giepmans, Ben,Goda, Sayed K.,D?mling, Alexander

supporting information, p. 5396 - 5400 (2020/07/08)

A concise and modular total synthesis of the highly potent N14-desacetoxytubulysin H (1) has been accomplished in 18 steps in an overall yield of up to 30percent. Our work highlights the complexity-augmenting and route-shortening power of diastereoselective multicomponent reaction (MCR) as well as the role of bulky ligands to perfectly control both the regioselective and diastereoselective synthesis of tubuphenylalanine in just two steps. The total synthesis not only provides an operationally simple and step economy but will also stimulate major advances in the development of new tubulysin analogues.

Stereoselective total synthesis of tubulysin v

Wang, Rui,Tian, Ping,Lin, Guoqiang

, p. 40 - 48 (2013/08/24)

The total synthesis of tubulysin V was accomplished in 1.0% overall yield with linear 13 steps. Our synthetic strategy featured the following two reactions. One is zinc-mediated aza-Barbier reaction of (R)-N-tert- butanesulfinyl imine 8 with β-ester group functionalized allylic bromide 9 to afford the chiral homo-allylic amine (7); the other is to employ the methodology of aqueous indium-mediated aza-Barbier reaction previously developed by our group, giving the chiral homo-allylic amine 13 with high efficiency.
