(+/-)-Ambreinolide is a sesquiterpene lactone found in the essential oil of the Ambrosia plant, which is commonly known as ragweed. It is a chiral compound, meaning it has two enantiomers, (+)-ambreinolide and (-)-ambreinolide, which are mirror images of each other. This organic compound is characterized by its unique structure and properties, which include a lactone ring and a conjugated diene system. (+/-)-Ambreinolide has been studied for its potential biological activities, such as anti-inflammatory and cytotoxic effects, and it is also used as a fragrance ingredient in the perfume industry due to its pleasant scent. The compound's natural occurrence and synthetic production have been subjects of research, with the aim of understanding its role in plant defense mechanisms and its potential applications in medicine and cosmetics.

7663-46-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7663-46-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,6 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7663-46:
(6*7)+(5*6)+(4*6)+(3*3)+(2*4)+(1*6)=119
119 % 10 = 9
So 7663-46-9 is a valid CAS Registry Number.

Total synthesis of (+/-)-syn-copalol.

Toshima, Hiroaki,Oikawa, Hideaki,Yada, Hiroshi,Ono, Hiroshi,Toyomasu, Tomonobu,Sassa, Takeshi

, p. 2504 - 2510 (2007/10/03)

The labdane diterpene derivative, syn-copalol [(+)-5] is the alcohol part of syn-copalyl diphosphate [(+)-4]. In this paper, racemic (+/-)-5 was synthesized from a known racemic lactone in 8 steps. The current and our previous syntheses provide all four copalol derivatives [(+)-3, (-)-3 and (+/-)-5] which are required for the biosynthetic study of polycyclic diterpenes.

New Syntheses of (+/-)-Ambrox, (+/-)-Ambra Oxide and Their Stereoisomers

Kawanobe,Tsuneo,Kogami, Kunio,Matsui, Masanao

, p. 1475 - 1480 (2007/10/02)

New and efficient syntheses of (+/-)-ambrox (1a), (+/-)-ambra oxide (2a) and their stereoisomers (1b, 2b ca. c), amber-like odorous compounds, are described.Starting from dihydro β- and α-ionone (5,12), these substances were obtained in only a few steps via stereoselective acid-catalized cyclization of monocyclodienoic acid (7a ca. b, 11a ca. b, 15a).
