676236-10-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 676236-10-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,2,3 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 676236-10:
(8*6)+(7*7)+(6*6)+(5*2)+(4*3)+(3*6)+(2*1)+(1*0)=175
175 % 10 = 5
So 676236-10-5 is a valid CAS Registry Number.

Highly efficient total synthesis of Δ12-PGJ2, 15-deoxy-Δ12,14-PGJ2, and their analogues

Acharya, Hukum P.,Kobayashi, Yuichi

, p. 3329 - 3343 (2007/10/03)

Palladium-catalyzed reaction of TBS ether of 4-cyclopentene-1,3-diol monoacetate (>95% ee) with an anion derived from methyl malonate and a base such as t-BuOK and LDA proceeded highly efficiently and reproducibly. The product obtained in >90% isolated yield was transformed in five steps into the key cyclopentenone possessing the α-chain at the γ position. Aldol reaction of this enone with the ω-chain aldehyde afforded the aldol adduct, and exposure of the derived mesylate to Al2O3 furnished the cross-conjugated dienone of the full structure. Finally, functional group manipulation furnished Δ12-PGJ2 efficiently. Similarly, 15-deoxy-Δ12,14-PGJ2, 5,6-acetylene analogues, and a 5,6-dihydro analogue were synthesized.

Page/Page column 24-25, (2010/02/15)

PROBLEM TO BE SOLVED: To provide a method for producing a prostaglandin derivative, the prostaglandin derivative and an intermediate compound therefor, especially a method for producing a δ-12-prostaglandin J2 derivative using a new method for chemical synthesis through the intermediate compound. SOLUTION: The method for production is a method for producing the prostaglandin derivative using (1R,3R)-4-cyclopentene-1,3-diol 3-acetate (carboxylate) as a starting material. The method is composed of (A) an α-side chain introduction step of providing a malonic acid ester addition compound at the 3-position of the (1R,3R)-4-cyclopentene-1,3-diol, (B) an α-side chain extension step of affording a (1R,3R)-4-cyclopenten-1-one compound having the α-side chain of the prostaglandin derivative at the 3-position and (C) a prostaglandin derivative synthesizing step of conversion into the prostaglandin derivative.

Total synthesis of Δ12-PGJ2, 15-deoxy-Δ12,14-PGJ2, and related compounds

Acharya, Hukum P.,Kobayashi, Yuichi

, p. 1199 - 1202 (2007/10/03)

A key cyclopentenone possessing the α-chain was synthesized from TBS ether of 4-cyclopentene-1,3-diol monoacetate, and submitted to aldol reaction at the α′-position with the ω-chain aldehydes followed by dehydration to produce the title compounds. In a similar manner, 5-dehydro compounds (acetylene analogues) were synthesized successfully. In addition, palladium-catalyzed reaction of 4-cyclopentene-1,3-diol monoacetate with methyl malonate, the first step of the synthesis, was improved to afford the product in high yield by using t-BuOK or LDA in place of NaH.
