2589-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2589-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,8 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2589-81:
(6*2)+(5*5)+(4*8)+(3*9)+(2*8)+(1*1)=113
113 % 10 = 3
So 2589-81-3 is a valid CAS Registry Number.

Self-Condensation of Enaminodiones as a Method for Benzene Ring Construction: Synthesis of Diacyl-Substituted Phenols and Catechols

Obydennov, Dmitrii L.,Chernyshova, Elena V.,Sosnovskikh, Vyacheslav Y.

, p. 6491 - 6501 (2019/05/24)

A novel transition metal-free approach for the construction of the benzene core has been developed through self-condensation of available enaminodiones. Functionalized acyl-substituted phenols and catechols were obtained in 29-97% yields with high chemoselectivity under mild conditions. This base-promoted formal [4+2] annulation proceeds via cyclohexanone formation and involves the cascade transformation based on double Michael addition and aromatization (retro-Claisen cleavage and amine elimination).

A REEXAMINATION OF THE RETRO-FRIES REARRANGEMENT OF SOME o-HYDROXYKETONES

Martin, Robert,Lafrance, Jean Ronald,Demerseman, Pierre

, p. 539 - 548 (2007/10/02)

The retro-Fries rearrangement, catalyzed by protic and Lewis acids, was studied for some o-hydroxyketones.The results are consistent with the mechanism of an heterolytic cleavage and rearrangement.It appears that, in general, Lewis acids do not induce the retro-Fries rearrangement of o-hydroxyketones.However, in certain cases, it may be brought about the presence of a protic acid generated in situ, from a solvent-catalyst interaction.
