83-74-9 Usage
Description
This indole alkaloid occurs in the root of Tabernanthe iboga Baill. It was first
examined in detail by Raymond-Hamet who assigned to it the empirical formula
C19H24(26)ON2, now altered to that given above. The base forms colourless
crystals from EtOH and is laevorotatory with [Q1D - 53° (EtOH). It is insoluble
in Et20, slightly so in Me2CO or CHC1 3 but dissolves freely in MeOH, EtOH or
H20. The alkaloid yields a hydrochloride, m.p. 299°C (dec.); lQlhs - 67°
(MeOH) or - 37.3° (H20). It contains one methoxyl group and gives the typical
indole reactions. On distillation with Zn dust or soda-lime it furnishes products
which are indole derivatives with the ~-position free.
In a manner similar to that of cocaine, the alkaloid potentiates the pressor
action of adrenaline and abolishes the sino-carotid reflexes. Unlike cocaine,
however, it also augments the action of tyramine and that of dl-ephedrine to a
slight extent. Vincent and Sero have reported that it inhibits the action of serum
cholinesterase.
Purification Methods
Crystallise it from EtOH or aqueous EtOH and sublime it at 150o/0.01mm. It is soluble in organic solvents but insoluble in H2O. The hydrochloride, m 299-300o(dec), is soluble in H2O and alcohols. [Büchi et al. J Am Chem Soc 88 3099 1866, Rosenmund Chem Ber 108 1871 1975, Beilstein 23 III/IV 2742.]

Check Digit Verification of cas no
The CAS Registry Mumber 83-74-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83-74:
(4*8)+(3*3)+(2*7)+(1*4)=59
59 % 10 = 9
So 83-74-9 is a valid CAS Registry Number.

Biosynthesis of an Anti-Addiction Agent from the Iboga Plant

(-)-Ibogaine and (-)-voacangine are plant derived psychoactives that show promise as treatments for opioid addiction. However, these compounds are produced by hard to source plants, making these chemicals difficult for broad-scale use. Here we report the complete biosynthesis of (-)-voacangine, and de-esterified voacangine, which is converted to (-)-ibogaine by heating, enabling biocatalytic production of these compounds. Notably, (-)-ibogaine and (-)-voacangine are of the opposite enantiomeric configuration compared to the other major alkaloids found in this natural product class. Therefore, this discovery provides insight into enantioselective enzymatic formal Diels-Alder reactions.
NORIBOGAINE COMPOSITIONS

Page/Page column 15-16, (2012/02/05)
Disclosed are noribogaine compositions comprising a very high level of the 2(R), 4(S), 5(S), 6(S) and 18(R) enantiomer and not more than 0.5 wt% of ibogaine relative to the total amount of noribogaine.
