We’ll tell you more about this compound (cas:1001-26-9).

4-Aminoquinolines were prepared in a three-step synthesis starting from substituted anthranilonitriles. The condensation on 1,1,1-trichloro-4-ethoxybut-3-enone proceeded efficiently either neat or in refluxing EtOH. Cyclization in superacidic trifluoromethanesulfonic acid provided unstable intermediate, which upon treatment with NaOEt in ethanol, afforded the expected esters. Theor. investigations pointed out a monoprotonated nitrilium as the reactive species during the cyclization process.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Ethyl 3-Ethoxy-2-Propenoate(SMILESS: O=C(OCC)/C=C/OCC,cas:1001-26-9) is researched.Product Details of 60804-74-2. The article 《Effect of hydroxyurea on α-acetylenic esters》 in relation to this compound, is published in Canadian Journal of Chemistry. Let’s take a look at the latest research on this compound (cas:1001-26-9).

Hydroxyurea, in its oxanion form NH2CONHO-, reacts in basic medium via 1,4-addition to α-acetylenic esters, leading to the E- and Z-ethylenic β-ureidoxy ester isomers. The Z isomer cyclizes in situ to give 2-carboxamido-5-methyl-3-isoxazolone. With HCCCO2Ph, 3-hydroxy-5-phenylisoxazole is directly obtained without isolating the intermediate N-carboxamido derivative HCCCO2Et gave 2 cyclic compounds: 3-hydroxyisoxazole (I) and 2-carboxamido-5-ethoxy-3-isoxazolidinone (II). I formation is due to the in situ cyclization of the Z isomer. II formation can be explained by solvent addition to the E-β-ureidoxyacrylate intermediate in a Michael addition, followed by cyclization.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Bisbenzothieno[3,2-b:2′,3′-e]pyridines, published in 2004-09-30, which mentions a compound: 1001-26-9, Name is Ethyl 3-Ethoxy-2-Propenoate, Molecular C7H12O3, Name: Ethyl 3-Ethoxy-2-Propenoate.

Heating potassium 3-aminobenzo[b]thiophene-2-carboxylate with Et propiolate or Et 3-ethoxyacrylate in acetic acid yielded the Et 2-(6,12-Dihydro-bis[1]benzothieno[3,2-b:2′,3′-e]pyridin-6-yl)-acetate (I) as main product and 1,4-dihydro-[1]benzothieno[3,2-b]-4-pyridone as byproduct. The dihydropyridine (DHP) I was dehydrogenated with ammonium cerium nitrate (CAN) to give its pyridine derivative II. The half wave potential E1/2 = 1.64 V showed that I was much more stable against oxidizing agents than the reference compound nifedipine with E1/2 = 1.15 V. Alk. saponification of the acetic acid ester II did not yield the corresponding acetic acid, because decarboxylation took place to form the methylpyridine derivative

This work describes two distinct routes to prepare pyrazolo[1,5-α]pyrimidin-7-ones and two distinct routes to prepare pyrazolo[1,5-α]pyrimidin-5-ones. Use of 1,3-dimethyluracil as the electrophile in the preparation of the pyrimidin-5-one regioisomer represents a correction of previously reported results. Also, a novel reaction to prepare this isomer was identified and the reaction mechanism elucidated. This work provides the experimentalist with complimentary synthetic pathways that afford either the pyrimidin-7-one or the pyrimidin-5-one regioisomer.
