General Description

Ethyl cis-3-(acetamido)-2-butenoate is a chemical compound with the molecular formula C8H13NO3. It is an ester with a butenoate backbone and an acetamido group attached to the third carbon atom in a cis configuration. This chemical is commonly used in the flavor and fragrance industry as a food additive and aroma compound. It has a sweet, fruity odor and is often used to impart banana, strawberry, and pineapple flavors in various food and beverage products. Ethyl cis-3-(acetamido)-2-butenoate is also used in the pharmaceutical industry for its potential biological and pharmacological activities.

Check Digit Verification of cas no

The CAS Registry Mumber 23652-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,5 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 23652-56:
(7*2)+(6*3)+(5*6)+(4*5)+(3*2)+(2*5)+(1*6)=104
104 % 10 = 4
So 23652-56-4 is a valid CAS Registry Number.

Rh(I)-catalyzed enantioselective hydrogenation of (E)- and (Z)-beta-(acylamino)acrylates using 1,4-bisphosphine ligands under mild conditions.

Lee, Sang-gi,Zhang, Yong Jian

, p. 2429 - 2431 (2002)

[reaction: see text] Rh-Me-BDPMI (1a) complex can be an effective catalyst for the hydrogenations of (E)- and (Z)-beta-(acylamino)acrylates, in which the Z-isomers hydrogenated with the same or even higher ee values than the corresponding E-isomers. The conversion yield and enantioselectivity of E- and Z-isomers were largely dependent on the solvent, and thus, the E-isomers were hydrogenated more effectively in CH(2)Cl(2), whereas the Z-isomers were hydrogenated more effectively in polar MeOH solvent.

Hypervalent iodane mediated reactions of: N -acetyl enamines for the synthesis of oxazoles and imidazoles

Xu, Kang,Yang, Ruiqi,Yang, Shuang,Jiang, Cheng,Ding, Zhenhua

supporting information, p. 8977 - 8981 (2019/10/28)

A hypervalent iodane reagent used for the intramolecular cyclization of N-acetyl enamines and intermolecular cyclocondensation of enamines and nitriles was investigated. The reaction was performed under mild conditions and gave oxazoles and imidazoles, respectively, in moderate to excellent yields. This transformation exhibits good reactivity, selectivity and functional group tolerance. The selectivity of the intra- or intermolecular reaction is dependent on the structure of N-acetyl enamines.

Nickel-catalyzed enantioselective hydrogenation of β-(acylamino)acrylates: Synthesis of chiral β-amino acid derivatives

Li, Xiuxiu,You, Cai,Li, Shuailong,Lv, Hui,Zhang, Xumu

supporting information, p. 5130 - 5133 (2017/11/06)

The nickel-catalyzed asymmetric hydrogenation of β-(acylamino)acrylates has been developed, affording chiral β-amino acid derivatives with excellent yields (95-99% yield) and enantioselectivities (97-99% ee). With the Ni-Binapine system, high enantioselectivities (98-99% ee) have also been obtained in the hydrogenation of Z/E isomeric mixtures of β-alkyl and β-aryl β-(acylamino)acrylates. The synthesis of chiral β-amino acid derivatives on a gram scale has also been achieved with 0.2 mol % catalyst loading.
