Description
3-Hydroxy-1-methyl-5-pyridin-3-yl-pyrrolidin-2-one, also known as trans-3'-Hydroxycotinine (3HC), is a metabolite of nicotine derived from the metabolism of cotinine by the CYP2A6 enzyme. It is an N-alkylpyrrolidine with a hydroxy group substitution at position C-3 and exists as the 3R,5S-diastereomer. 3-hydroxy-1-methyl-5-pyridin-3-yl-pyrrolidin-2-one is characterized by its off-white to pale-yellow solid appearance and is commonly found in the urine of smokers and users of other tobacco or nicotine products.

Check Digit Verification of cas no
The CAS Registry Mumber 34834-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,3 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34834-67:
(7*3)+(6*4)+(5*8)+(4*3)+(3*4)+(2*6)+(1*7)=128
128 % 10 = 8
So 34834-67-8 is a valid CAS Registry Number.

Synthesis of (3′R,5′S)-3′-hydroxycotinine using 1,3-dipolar cycloaddition of a nitrone

To synthesize (3′R,5′S)-3′-hydroxycotinine [(+)-1], the main metabolite of nicotine (2), cycloaddition of C-(3-pyridyl)nitrones 3a, 3c, and 15 with (2R)- and (2S)-N-(acryloyl)bornane-10,2-sultam [(2R)- and (2S)-8] was examined. Among them, l-gulose-derived nitrone 15 underwent stereoselective cycloaddition with (2S)-8 to afford cycloadduct 16, which was elaborated to (+)-1. Graphical Abstract
Synthesis of (3'R,5'S)-trans-3'-hydroxycotinine, a major metabolite of nicotine. Metabolic formation of 3'-hydroxycotinine in humans is highly stereoselective
Jacob III,Shulgin,Benowitz
, p. 1888 - 1891 (2007/10/02)
A method for the synthesis of (3'R,5'S-trans-3'-hydroxycotinine, a major metabolite of nicotine in humans, is described. The method involves deprotonation of (S)-cotinine with lithium diisopropylamide (LDA) followed by oxidation with the transition metal peroxide oxodiperoxymolybdenum (pyridine)(hexamethylphosphoric triamide)(MoOPH) to give an 80:20 mixture of trans-/cis-3'-hydroxycotinine. The pure (>98%) trans isomer is obtained by conversion to the solid hexanoate ester, recrystallization, and cleavage of the ester by heating with n-butylamine. GC-MS analysis of urine extracts from several smokers indicated that in humans metabolic 3'-hydroxycotinine is 95-98% trans.
