1H-Pyrrole-2,5-dicarboxylic acid, 3,4-dimethyl-, 2,5-diethyl ester is a complex organic compound with the chemical formula C11H14N2O4. It is a derivative of 1H-pyrrole-2,5-dicarboxylic acid, featuring two ester groups at the 2 and 5 positions, with diethyl substituents. The molecule also has two methyl groups at the 3 and 4 positions, which contribute to its structure and properties. 1H-Pyrrole-2,5-dicarboxylicacid, 3,4-dimethyl-, 2,5-diethyl ester is characterized by its unique molecular structure, which includes a pyrrole ring, a five-membered aromatic ring with one nitrogen atom. The presence of the diethyl ester groups and dimethyl substituents influences its reactivity, solubility, and potential applications in various chemical and pharmaceutical processes.

2199-55-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2199-55-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2199-55:
(6*2)+(5*1)+(4*9)+(3*9)+(2*5)+(1*5)=95
95 % 10 = 5
So 2199-55-5 is a valid CAS Registry Number.

A direct preparation of N-unsubstituted pyrrole-2,5-dicarboxylates from 2-Azidocarboxylic esters

Ciez, Dariusz

supporting information; experimental part, p. 4282 - 4285 (2010/01/16)

A new and easy method for synthesis of symmetric pyrrole-2,5-dlcarboxylate derivatives via a simple tltanium(IV)-medlated oxidative dimerlzation of 2-azldocarboxyllc esters is described. The process involves a transformation of tltanium(IV) enolates into

ELECTROPHILIC HETEROAROMATIC SUBSTITUTIONS. X. UNEXPECTED RESULTS IN THE α-SIDE-CHAIN CHLORINATION OF A SERIES OF ETHYL 3,4,5-TRIALKYLPYRROLE-2-CARBOXYLATES

Scarsella, Marco,Sleiter, Giancarlo

, p. 757 - 762 (2007/10/02)

The reaction of a series of 3,4,5-trialkyl-substituted ethyl pyrrole-2-carboxylates with an excess of sulphuryl chloride followed by solvolysis has been investigated in several solvents and under different experimental conditions.In all cases, beside the expected α-side-chain substituted product, substantial amounts of derivatives functionalised also in a β-side chain have been isolated and identified.The process turned out to be electrophilic in nature and to involve allylic migration of the halogen from the α-sigma adduct to the adjacent β-side chain.Virtually identical results have been obtained when elemental chlorine was used.

Alkylation process

, (2008/06/13)

Substituted pyrrole compounds, such as 3-ethyl-4-methyl-5-carbethoxy pyrrole, 2,4-dimethyl-3-acetyl pyrrole and 2-methyl-5-carboxy pyrrole-4-propionic acid diethyl ester, are alkylated in a single step by reaction with an aldehyde or ketone in the presence of both an acid condensing agent such as hydriodic acid and a compatible reducing agent such as metallic zinc or stannous chloride. Suitable carbonyl reactants include formaldehyde, paraldehyde, isobutyraldehyde, acetone, cyclohexanone and methyl-isobutyl ketone. This application is a continuation application of U.S. application Ser. No. 281,624 filed Aug. 18, 1972, now abandoned, which is a continuation-in-part application of U.S. application Ser. No. 832,001, filed June 10, 1969, now abandoned.
