(3β,16E,20β)-16,17-Didehydro-17-methoxycorynan-16-carboxylic acid methyl ester is a complex organic compound with the molecular formula C21H26O5. It is a derivative of corynan, a class of natural products found in plants, particularly in the family Rubiaceae. This specific compound features a 16,17-didehydro group, which means there is a double bond between carbons 16 and 17, and a 17-methoxy group, indicating a methoxy (-OCH3) functional group attached to carbon 17. The compound also has a carboxylic acid group at the 16th carbon, which is esterified with a methyl group, forming a methyl ester. This chemical structure contributes to its potential biological activities and applications in the field of natural product chemistry and pharmacology.

7729-22-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7729-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7729-22:
(6*7)+(5*7)+(4*2)+(3*9)+(2*2)+(1*2)=118
118 % 10 = 8
So 7729-22-8 is a valid CAS Registry Number.

Total synthesis of (±)-hirsutine: Application of phosphine-catalyzed imine-allene [4 + 2] annulation

Villa, Reymundo A.,Xu, Qihai,Kwon, Ohyun

, p. 4634 - 4637 (2012/10/30)

The total synthesis of the indole alkaloid hirsutine has been achieved, with a key step being the application of our phosphine-catalyzed [4 + 2] annulation of an imine with ethyl α-methylallenoate. From commercially available indole-2-carboxaldehyde, the target was synthesized in 14 steps and 6.7% overall yield.

Stereoselective Total Synthesis of (+/-)-Hirsutine and Related Corynanthe Alkaloids

Brown, Richard T.,Jones, Martin F.,Wingfield, Mark

, p. 847 - 848 (2007/10/02)

In a completely stereoselective sequence, an analogue of dihydrosecologanin aglucone has been synthesised via a novel cyclopentenedione dimer and converted into tetracyclic indole alkaloids.
