ω-Acetyllongifolene is a sesquiterpene ketone found in the essential oils of various plants, particularly in the Longifolene chemotype of the Juniperus communis, commonly known as common juniper. It is characterized by its unique molecular structure, which includes a ketone group attached to a sesquiterpene backbone. ω-acetyllongifolene is known for its potential anti-inflammatory and antimicrobial properties, making it a subject of interest in the field of natural product chemistry and pharmacology. The study of ω-acetyllongifolene and its derivatives could lead to the development of new therapeutic agents, particularly in the area of infectious diseases and inflammatory conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 3338-56-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3338-56:
(6*3)+(5*3)+(4*3)+(3*8)+(2*5)+(1*6)=85
85 % 10 = 5
So 3338-56-5 is a valid CAS Registry Number.

Kondakof Acylation of Logifolene/Camphene: A Comparative Study Using Boron Trifluoride Etherate/Stannic Chloride as Catalysts

Dalavoy, V. S.,Deodhar, V. B.,Nayak, U. R.

, p. 907 - 910 (2007/10/02)

The Kondakof acylation of the ectocyclic methylene moiety in comphene (1) and its isoprene homologue longifolene (2) has been studied in acetic anhydride using BF3*OEt2/SnCl4 as catalysts.Ac2O-BF3*OEt2 fails to acylate (1) but gives isobornylacetate (3) (46percent) as the sole product.Acylation of (1) with Ac2O-SnCl4 affords ω-acetyl comphene (4) in a negligible yield (2percent) along with (3) in a much reduced yield (19percent).In sharp contrast, longifolene (2) generates ω-acetyllongifolene (5) with both the catalysts: BF3*OEt2 (24percent) and SnCl4 (16percent).The other compounds isolated in the former case are isolongifolene (6) (50percent) and transannular acetate (7) (2percent); in the latter case, (6) (17percent), (7) (5percent) and the novel tetracyclic methylketone (8) (11percent) are the co-products.The precurser for (8) has been shown to be the isomerized hydrocarbon (6), on direct acylation with SnCl4 generates (8).
