4795-87-3

(+)-Winterin is a naturally occurring chemical compound found in the plant species Cynanchum paniculatum, which is commonly known as the Swallow-wort. This plant is native to China and has been used in traditional Chinese medicine for its potential therapeutic properties. (+)-Winterin is a sesquiterpene lactone, a type of organic compound characterized by a 15-carbon skeleton and a lactone ring. It has been studied for its potential anti-inflammatory, analgesic, and anti-cancer properties, although more research is needed to fully understand its effects and potential applications in medicine. The compound's name, (+)-winterin, indicates its specific stereochemistry, with the "+" sign denoting the configuration of the molecule's chiral center.

4795-87-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4795-87-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,9 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4795-87:
(6*4)+(5*7)+(4*9)+(3*5)+(2*8)+(1*7)=133
133 % 10 = 3
So 4795-87-3 is a valid CAS Registry Number.

Influence of Electron Donating Aromatic Substituents on the Ruthenium Tetroxide-Catalysed Oxidation of (+/-)-Podocarpa-8,11,13-trienes

Ghosh, Sukumar,Ghatak, Usha Ranjan

, p. 7289 - 7296 (2007/10/02)

Whereas the (+/-)-podocarpa-8,11,13-trienes 3b-e, incorporating a phenolic hydroxyl or methyl ether functionality at C-11 and C-14, and C-14 respectively, on oxidation with sodium metaperiodate - catalyzed by ruthenium tetroxide give (+/-)-winterin, through chemoselective degradation of the aromatic ring, the unsubstituted 3a, isomeric methyl ethers 3f-i, and cis-podocarpa-8,11,13-triene undergo only benzylic oxidation resulting in the respective ketones 8d, 8a-c, 8e and the diketone 9.Similar oxidation reaction of the hexahydrophenanthrene 7a led to the α,β-unsaturated tricyclic ketone 11a and the tetrahydronaphthalene dicarboxylic anhydride 12.In contrast, 7b produced the diketone 10b and the α,β-unsaturated ketone 11b as the sole isolated products.

Synthesis of Winterin from Podocarpic Acid

Ozonolysis of a hydroquinone derived from podocarpic acid (1) gave the biologically active natural product winterin (11).Treatment of the quinone (12) with ozone bave a ring-contracted spiro furanone, the mechanism of formation of which is proposed.

The drimane sesquiterpenes (+)-winterin, (+)-confertifolin, (+)-isodrimenin, and (+)-bicyclofarnesol were synthesised starting from royleanone, an abietane diterpenoid easily available as a main constituent of the root of some Salvia species.

OZONOLYSIS OF PHENOLIC DEHYDROABIETANE DERIVATIVES. - SYNTHESES OF OPTICALLY ACTIVE (+)-CONFERTIFOLIN, (+)-VALDIVIOLIDE, (+)-WINTERIN, (+)-ISODRIMERIN, AND (+)-PALLESCENSIN A-

Akita, Hiroyuki,Oishi, Takeshi

, p. 1580 - 1587 (2007/10/02)

Ozonolysis of phenolic dehydroabietane derivatives was investigated and the products obtained by cleavage of the aromatic ring were found to be determined by the hydroxyl substitution pattern of the aromatic C-ring.Ozonolysis of the 12-hydroxy compound (ferruginol (12) gave pentanorlabdane-type compounds (14, 15, and 16).Ozonolysis of the 11-hydroxy derivative (18) and/or the 14-hydroxy derivatives (19 and 20 afforded optically active drimanic sesquiterpenes ((+)-isodrimenin (8), (+)-confertifolin (7), (+)-valdiviolide (9), and (+)-winterin (10) in one step.In this case, the mode of cleavage was different from that of 12.On the other hand, ozonolysis of the 13-hydroxy compound (3) caused cleavage in yet another manner to give the butenolide (23), which was easily converted into optically active pallescensin A (11).The mechanisms of the cleavage reactions are discussed.Keywords: - aromatic ring cleavage; ozonolysis; drimanic sesquiterpenes; phenolic diterpenes; catechol
