85613-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 85613-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,1 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85613-04:
(7*8)+(6*5)+(5*6)+(4*1)+(3*3)+(2*0)+(1*4)=133
133 % 10 = 3
So 85613-04-3 is a valid CAS Registry Number.

Synthesis of methoxylated goniothalamin, aza-goniothalamin and γ-pyrones and their in vitro evaluation against human cancer cells

Barcelos, Rosimeire Coura,Pastre, Julio Cezar,Caixeta, Vanessa,Vendramini-Costa, Débora Barbosa,De Carvalho, Jo?o Ernesto,Pilli, Ronaldo Aloise

experimental part, p. 3635 - 3651 (2012/07/27)

The present work describes the preparation of three novel series of compounds based on the structure of goniothalamin, a natural styryl lactone which has been found to display cytotoxic and antiproliferative activities against a variety of cancer cell lines. A focused library of 29 novel goniothalamin analogues was prepared and evaluated against seven human cancer cell lines. While the γ-pyrones and the aza-goniothalamin analogues were less potent than the lead compound, 2,4-dimethoxy analogue 88 has shown to be more potent in vitro than goniothalamin against all cancer cell lines evaluated. Furthermore, it was more potent than doxorubicin against NCI-ADR/RES, OVCAR-03 and HT-29 while being less toxic to human keratinocytes (HaCat). The 3,5-dimethoxy analogue 90 and 2,4,5-trimethoxy analogue 92 also displayed promising antiproliferative activity when compared to goniothalamin (1). These results provide new elements for the design and synthesis of novel representatives of this family of natural compounds.

Competitive [2,3]-and [1,2]-oxonium ylide rearrangements. Concerted or stepwise?

Jaber, Deana M.,Burgin, Ryan N.,Helper, Matthew,Zavalij, Peter Y.,Doyle, Michael P.

supporting information; experimental part, p. 1676 - 1679 (2012/06/30)

The axial-equatorial conformational isomer distribution of the reactant diazoacetoacetate or its metal carbene intermediate is reflected in Rh(II) catalyzed oxonium ylide forming reactions of 3-(trans-2-arylvinyl) tetrahydropyranone-5-diazoacetoacetates that afford diastereoisomeric products for both the symmetry-allowed [2,3]-and the formally symmetry-forbidden [1,2]-oxonium ylide rearrangements.

A Lewis Base-catalyzed hetero Diels-Alder reaction between aldehydes and the Danishefsky's diene

Mukaiyama, Teruaki,Kitazawa, Takayuki,Fujisawa, Hidehiko

, p. 328 - 329 (2007/10/03)

A lithium methoxide-catalyzed hetero Diels-Alder reaction of aromatic and aliphatic aldehydes with 1-methoxy-3-trimethylsilyloxy-1,3-butadiene (Danishefsky's diene) is described. It proceeds through the Mukaiyama-Aldol reaction pathway and affords the cor

Hetero diels-alder type reactions between danishefsky's dienes in the presence of lewis base catalysts. An efficient method for the synthesis of substituted 2,3-dihydropyran-4-ones

Kitazawa, Takayuki,Mukaiyama, Teruaki

, p. 417 - 427 (2008/02/09)

Alkoxy anion such as methoxide anion works effectively as Lewis base catalyst to activate silicon-carbon bond of 1-methoxy-3-trimethylsilyloxy-1,3-butadiens (Danishefsky's dienes) in the reaction between aldehydes and ketones. By using Lewis base as catal

ON THE MECHANISM OF THE LEWIS ACID CATALYZED CYCLOCONDENSTION OF ALDEHYDES WITH SILOXYDIENES

Larson, Eric R.,Danishefsky, Samuel

, p. 1975 - 1978 (2007/10/02)

Competing cycloaddition versus aldolization-cyclization processes are demonstrated in the formation of 6-styryl-5,6-dihydro-γ-pyrone via the BF3 catalyzed reaction of cinnamaldehyde with trans-1-methoxy 3-trimethylsilyloxy-1,3-butadiene.
