Corysamine chloride, also known as Berbinium or by its chemical descriptor 7,8,13,13a-tetradehydro-13-methyl-2,3:9,10-bis(methylenedioxy)- (8CI), is a protoberberine alkaloid that serves as a key intermediate in the biomimetic synthesis of hexahydrobenzo[c]phenanthridine alkaloids such as corynoline, epicorynoline, isocorynoline, and epiisocorynoline. Its structural features enable efficient transformation into these target compounds through oxidative and reductive steps, highlighting its utility as a precursor in synthetic alkaloid chemistry.

30243-28-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30243-28-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,2,4 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 30243-28:
(7*3)+(6*0)+(5*2)+(4*4)+(3*3)+(2*2)+(1*8)=68
68 % 10 = 8
So 30243-28-8 is a valid CAS Registry Number.

A General, Concise Strategy that Enables Collective Total Syntheses of over 50 Protoberberine and Five Aporhoeadane Alkaloids within Four to Eight Steps

Zhou, Shiqiang,Tong, Rongbiao

supporting information, p. 7084 - 7089 (2016/05/19)

A concise, catalytic, and general strategy that allowed efficient total syntheses of 22 natural 13-methylprotoberberines within four steps for each molecule is reported. This synthesis represents the most efficient and shortest route to date, featuring three catalytic processes: CuI-catalyzed redox-A3 reaction, Pd-catalyzed reductive carbocyclization, and PtO2-catalyzed hydrogenation. Importantly, this new strategy to the tetracyclic framework has also been applied to the collective concise syntheses of >30 natural protoberberines (without 13-methyl group) and five aporhoeadane alkaloids.
