57200-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57200-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,0 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57200-23:
(7*5)+(6*7)+(5*2)+(4*0)+(3*0)+(2*2)+(1*3)=94
94 % 10 = 4
So 57200-23-4 is a valid CAS Registry Number.

Stille reactions of 2,3-bis(stannyl)butenoates: An unexpected regioselectivity

Carter, Neil B.,Mabon, Ross,Sweeney

, p. 1577 - 1579 (2006)

The palladium-catalyzed cross-coupling reaction of methyl (Z)-2,3-bis(tributylstannyl)butenoate with aryl iodides is regioselective, leading to 2-aryl-3-stannylated products; this selectivity is the opposite to that observed in the reaction between halide

An evaluation of palladium-based catalysts for the base-free borylation of alkenyl carboxylates

Gaube, Gregory,Leitch, David C.,Pipaon Fernandez, Nahiane

, p. 20095 - 20098 (2021/11/22)

Synthesis of organoboron derivatives is a key application of catalytic cross-coupling, with the Pd-catalyzed Miyaura borylation among the most versatile methods available. We have evaluated several Pd-based systems for borylation of alkenyl acetates and p

Synthesis method of butene lactone compound

-

Paragraph 0038-0048, (2021/12/07)

The invention discloses a synthesis method of a butene lactone compound, which comprises the following steps: adding an acrylic acid compound, paraformaldehyde, pentamethyl cyclopentadienyl carbonyl cobalt diiodide, AgSbF6 and sodium acetate into an organic solvent, heating under an air condition to react, and after the reaction is completed, performing post-treatment to obtain the butene lactone compound. According to the method, the butene lactone compound is synthesized from simple and easily available raw materials through a one-pot method, the conversion efficiency is high, and the step economy is good; meanwhile, the synthesis method is simple to operate, high in reaction yield and wide in substrate universality.

Chemoselective formal β-functionalization of substituted aliphatic amides enabled by a facile stereoselective oxidation event

Bauer, Adriano,Maulide, Nuno

, p. 9836 - 9840 (2019/11/11)

Aliphatic C-H functionalization is a topic of current intense interest in organic synthesis. Herein, we report that a facile and stereoselective dehydrogenation event enables the functionalization of aliphatic amides at different positions in a one-pot fa
