28319-79-1 Usage

General Description

20-oxopregna-5,7-dien-3-yl acetate is a chemical compound whose structure is related to certain types of steroids. It is characterized by the presence of a pregnane skeleton, which is a type of steroid structure that contains 21 carbon atoms arranged in three rings. This makes it part of a wider group of organic compounds known as terpenoids. The '20-oxo' in its name implies the presence of a ketone group (double-bonded oxygen atom) at the 20th carbon in the pregnane skeleton, while the 'acetate' indicates an acetyl group attached through an ester linkage. However, there is limited readily available information on its specific properties, uses, or biological activities, suggesting it could be primarily of interest within scientific research contexts.

Check Digit Verification of cas no

The CAS Registry Mumber 28319-79-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,1 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28319-79:
(7*2)+(6*8)+(5*3)+(4*1)+(3*9)+(2*7)+(1*9)=131
131 % 10 = 1
So 28319-79-1 is a valid CAS Registry Number.

Biogenesis-Guided Synthesis and Structural Revision of Sarocladione Enabled by Ruthenium-Catalyzed Endoperoxide Fragmentation

Ning, Yuhan,Tian, Hailong,Gui, Jinghan

supporting information, p. 11222 - 11226 (2021/04/19)

Sarocladione is the first 5,10:8,9-diseco-steroid with a 14-membered macrocyclic diketone framework to have been isolated from a natural source. Herein we report a biomimetic synthesis of sarocladione in only two or seven steps from inexpensive, commercially available ergosterol. The key feature of this synthesis was a novel ruthenium-catalyzed endoperoxide fragmentation, which transformed various saturated endoperoxides into olefinic diketones by cleavage of two C?C bonds. This synthesis allowed us to unambiguously determine the structure of sarocladione and provided experimental support for its revised biosynthetic origin. This work also vividly demonstrates that consideration of the biogenesis is a powerful tool for elucidating the structures of natural products.
