52789-75-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52789-75-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,8 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52789-75:
(7*5)+(6*2)+(5*7)+(4*8)+(3*9)+(2*7)+(1*5)=160
160 % 10 = 0
So 52789-75-0 is a valid CAS Registry Number.

Formation of δ-Lactones by cyanide catalyzed rearrangement of α-Hydroxy-β-oxoesters

Kieslich, David,Christoffers, Jens

supporting information, p. 953 - 957 (2021/02/06)

δ-Valerolactone derivatives are formed by cyanide-catalyzed ring-transformation of cyclic α-hydroxy-β-oxoesters. This unprecedented reaction defines a new synthetic methodology, and the products are obtained in up to quantitative yields. Several alkyl substitutions as well as different ester residues are tolerated. Furthermore, benzo- and heteroarene-annulated starting materials are converted without problems. As an additional benefit, the starting materials are straightforwardly accessed by cerium-catalyzed aerobic α-hydroxylation of readily available β-oxoesters.

Thermal and photochemical oxidation of 2-acetylcyclopentanone with atmospheric oxygen

Novikov,Shestak

, p. 1099 - 1110 (2013/07/26)

The major products of thermal (acetone, CaCl2 excess, reflux) and photochemical (acetone or CCl4, room temperature) oxidation of 2-acetylcyclopentanone with atmospheric oxygen are 2-acetyl-2- hydroxycyclopentanone, 2-acetyl-2-hydroxy

The Chemistry of Aryllead(IV) Tricarboxylates. Reaction with Enamines

May, George L.,Pinhey, John T.

, p. 1859 - 1871 (2007/10/02)

The treatment of 1-morhpholinocyclopentene (1a) with p-methoxyphenyllead triacetate (2a) in chloroform provides a simple high-yielding route to 2-(4-methoxyphenyl)cyclopentanone (3a).This arylation reaction of enamines has been investigated with a variety of substrates and a number of aryllead triacetates.The reaction has been found to be very sensitive to steric effects and is thus a useful synthetic method in a relatively small number of cases.Acetoxylation is a major competing reaction with those enamines of cyclic ketones which give a low to moderate yield of arylated product.
