139122-81-9 Usage

Definition

ChEBI: A kaurane diterpenoid that is (5beta,8alpha,13alpha)-18,20-epoxykauran-18-one substituted by a hydroxy group at position 16. Isolated from the roots of Tripterygium wilfordii, it exhibits anti HIV activity.

Check Digit Verification of cas no

The CAS Registry Mumber 139122-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,2 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139122-81:
(8*1)+(7*3)+(6*9)+(5*1)+(4*2)+(3*2)+(2*8)+(1*1)=119
119 % 10 = 9
So 139122-81-9 is a valid CAS Registry Number.

Syntheses of (-)-Tripterifordin and (-)-Neotripterifordin from Stevioside

Kobayashi, Shoji,Shibukawa, Keisuke,Hamada, Yoshiki,Kuruma, Takuma,Kawabata, Asako,Masuyama, Araki

, p. 1606 - 1613 (2018)

We report short syntheses of (-)-tripterifordin and (-)-neotripterifordin, potent inhibitors of HIV replication, from stevioside, a natural sweetener used worldwide. The key transformations are reduction at C13 through the formation of a tertiary chloride and subsequent three-step lactonization including a selective iodination at C20 by the photoreaction of the C19-alcohol. The title compounds were reliably obtained from stevioside in 9 and 11 steps (with 5-7 isolation steps), respectively. Additionally, the related lactone-containing ent-kaurenes, doianoterpenes A and B, and two more natural products were synthesized.
