63807-86-3 Usage

General Description

7-(4-Hydroxyphenyl)-2,2-dimethyl-2H,6H-benzo[1,2-b:5,4-b']dipyran-6-one, also known as sappanone A, is a naturally occurring compound found in the heartwood of Caesalpinia sappan, a plant native to Southeast Asia. It is a member of the benzo[1,2-b:5,4-b']dipyran-6-one family and is known for its antioxidant and anti-inflammatory properties. Sappanone A has been studied for its potential therapeutic applications, including its ability to inhibit the activity of enzymes involved in inflammation and its potential use in the treatment of conditions such as cancer, diabetes, and cardiovascular disease. Additionally, sappanone A has been found to have antimicrobial and antiviral properties, making it a promising candidate for the development of new pharmaceutical compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 63807-86-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,0 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63807-86:
(7*6)+(6*3)+(5*8)+(4*0)+(3*7)+(2*8)+(1*6)=143
143 % 10 = 3
So 63807-86-3 is a valid CAS Registry Number.

SYNTHESIS OF ERYTHRININ A, A NATURALLY OCCURING PYRANOISOFLAVONE

Suresh, R. V.,Iyer, C. S. Rukmani,Iyer, P. R.

, p. 2479 - 2482 (2007/10/02)

Erythrinin A (10) has been synthesised by the oxidative rearrangement of dihydropyranochalcone 1 with thallium(III)nitrate (TTN) in trimethyl orthoformate (TMOF) to the dimethyl acetal 2, followed by cyclisation to 3, demethylation to 6 and dehydrogenation.Compound 10 could also be obtained from chalcone 4 on similar rearrangement followed by cyclisation, demethoxymethylation and dehydrogenation.In another route, chalcone 7 was oxidatively rearranged with TTN in TMOF, to 8 which on treatment with HCl yielded 10.

THALLIUM(III) NITRATE MEDIATED SYNTHESIS OF ERYTHRININ-A, DIHYDROPYRANO- AND PYRANOISOFLAVONES

Suresh, Raghava Venkataramanna,Iyer, Chandrashekarapuram Subraman.,Iyer, Parameswaran Ramasubramonia

, p. 859 - 865 (2007/10/02)

Oxidative rearrangement of dihydropyranochalcones using thallium(III) nitrate-trimethylorthoformate (TTN-TMOF) reagent followed by acid catalysed cyclization yields the corresponding dihydropyranoisoflavones in good yields.Dehydrogenation of these isoflavones gave pyranoisoflavones.Demethylation of isoflavone (7) followed by dehydrogenation gave erythrinin-A (16).
