General Description

(-)-Humulene epoxide II is a natural organic compound that belongs to the class of sesquiterpenes, commonly found in hops and cannabis plants. It is a bicyclic sesquiterpene oxide with a characteristic woody and earthy aroma. (-)-Humulene epoxide II has been studied for its potential pharmacological properties, such as its anti-inflammatory and antinociceptive effects. Some research suggests that (-)-Humulene epoxide II may also have potential anticancer properties. Additionally, it is known to exhibit antimicrobial and antioxidant properties, making it a compound of interest for various applications in the pharmaceutical and natural products industries.

Check Digit Verification of cas no

The CAS Registry Mumber 19888-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,8 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19888-34:
(7*1)+(6*9)+(5*8)+(4*8)+(3*8)+(2*3)+(1*4)=167
167 % 10 = 7
So 19888-34-7 is a valid CAS Registry Number.

Erratum: Removal of the E-Olefin Barrier of Humulene Leading to Unnatural Terpenoid-like Skeletons (Organic Letters (2018) 20, 22, (7313-7320) DOI: 10.1021/acs.orglett.8b03259)

supporting information, p. 1241 - 1241 (2019/05/16)

The structures of compounds 11 and 12 shown in Figure 2A were corrected by changing the relative configurations, although the structures in the Supporting Information were correct. Figure 2A is corrected as follows: The absolute configurations of compounds 15-19 drawn in Figure 3A and in the Supporting Information were corrected. Although the relative configurations shown in the Supporting Information were correct, the wrong assignment is because of drawing the absolute configuration at the C-6 position of 15- 17 in reverse. The corrected Figure 3A is as follows and and the revised Supporting Information with the corrected structures for compounds 15-17 is included with this Correction.

Where is the Oxygen? Structural Analysis of α-Humulene Oxidation Products by the Crystalline Sponge Method

Zigon, Nicolas,Hoshino, Manabu,Yoshioka, Shota,Inokuma, Yasuhide,Fujita, Makoto

supporting information, p. 9033 - 9037 (2015/08/03)

Crystal structures of α-humulene, a cyclic sesquiterpene, and its oxidized subproducts, were analyzed by the crystalline sponge method. Regio- and stereochemistry, including absolute configuration when a chiral oxidant was applied, and the stable conformations of all the scaffold-related compounds were successfully determined for samples on a 5-50 μg scale.

A stable rearrangement product of humulene-4,5-epoxide

Carman, Raymond M.

, p. 1441 - 1442 (2008/09/20)

Humulene-4,5-monoepoxide, 1, may rearrange to the cyclopropyl diol 2 during chromatography over silica. The rearrangement can be reversed with acid.
