General Description
Protostephanone is a natural chemical compound found in certain plant species, particularly in the genus of Stephania. It is a yellow crystalline solid with a slightly floral and fruity odor. Protostephanone has been studied for its potential medicinal properties, including its anti-inflammatory and anti-cancer effects. It has also been used as a fragrance and flavoring agent in the cosmetic and food industries. Protostephanone is of interest to researchers and scientists for its potential therapeutic applications and its unique chemical structure, which makes it a promising candidate for further drug development and scientific exploration.
Check Digit Verification of cas no
The CAS Registry Mumber 20824-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,2 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20824-18:
(7*2)+(6*0)+(5*8)+(4*2)+(3*4)+(2*1)+(1*8)=84
84 % 10 = 4
So 20824-18-4 is a valid CAS Registry Number.

Synthesis along Biosynthetic Pathways. Part 2. Synthesis of Protostephanine

The dienone protostephanone (3) is synthesised by phenol coupling or by Pschorr cyclisation from readily prepared tetrahydroisoquinolines, and the corresponding dienols (17) and (18) are converted by rearrangement, fragmentation, and reduction into protostephanine (4).This sequence mimics the natural pathway to the alkaloid.
