The chemical compound "(4aS)-3,4,4a,9,10,10aα-Hexahydro-6-hydroxy-1,1,4a-trimethyl-7-isopropylphenanthren-2(1H)-one" is a complex organic molecule with a unique structure. It belongs to the class of phenanthrenones, which are derivatives of phenanthrene, a polycyclic aromatic hydrocarbon. This specific compound features a hexahydro ring system, indicating the presence of six hydrogen atoms in its cyclic structure. It also contains a hydroxyl group at the 6-position, which contributes to its reactivity and solubility properties. The molecule is further characterized by the presence of three methyl groups and an isopropyl group, which are responsible for its distinct steric and electronic properties. The compound's stereochemistry is defined by the '4aS' configuration, which specifies the arrangement of atoms around the chiral center at the 4a position. (4aS)-3,4,4a,9,10,10aα-Hexahydro-6-hydroxy-1,1,4a-trimethyl-7-isopropylphenanthren-2(1H)-one is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of more complex molecules or as a compound of interest in pharmaceutical or materials science research.

Check Digit Verification of cas no

The CAS Registry Mumber 472-37-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 472-37:
(5*4)+(4*7)+(3*2)+(2*3)+(1*7)=67
67 % 10 = 7
So 472-37-7 is a valid CAS Registry Number.

TERPENOIDS FROM LEAVES OF JUNIPERUS THURIFERA

San Feliciano, A.,Medarde, M.,Lopez, J. L.,Corral, J. M. Miguel Del,Puebla, P.,Barrero, A. F.

, p. 2241 - 2248 (1988)

Juniperus thurifera; Cupressaceae; diterpenoids; labdanes; pimaranes; abietanes; chemotaxonomy.Nineteen diterpenoids of the labdane, pimarane and abietane skeletons and four known sesqiterpenoids were isolated from Juniperus thurifera leaves.Thirteen of these diterpenoids are described for the first time as natural products.Their structures were elucidated principally by NMR techniques and chemical transformations.

Synthesis of (+)-Hinokiol, (+)-Hinokione, (+)-Salviol, and (+)-2-Oxoferruginol

Matsumoto, Takashi,Usui, Shuji,Kawashima, Hiroyuki,Mitsuki, Masanori

, p. 581 - 584 (2007/10/02)

Reduction of abieta-5,8,11,13-tetraen-3-one with lithium aluminium hydride afforded the corresponding alcohol, which was submitted to catalytic hydrogenation to yield abieta-8,11,13-trien-3β-ol (7) together with its 5βH-isomer.Acetylation of 7, followed by the Friedel-Crafts acylation, afforded 3β-acetoxy-12-acetylabieta-8,11,13-triene.This compound was converted into 3β,12-diacetoxyabieta-8,11,13-triene (11) by the Baeyer-Villiger oxidation.Treatment of 11 with lithium aluminium hydride yielded hinokiol, which was oxidized to hinokione.Subsequently, hinokiol was methylated and the resulting 12-methyl ether was dehydrated to afford 12-methoxyabieta-2,8,11,13-tetraene.The tetraene was then submitted to hydroboration-oxidation to give 12-methoxyabieta-8,11,13-trien-2α-ol (15) which, on demethylation with ethanethiol and anhydrous aluminium chloride, afforded salviol.Oxidation of 15 with pyridinium chlorochromate, followed by demethylation, gave 2-oxoferruginol.
