Ethyl 5-(4-Bromophenyl)-4-methyl-1H-pyrrole- 2-carboxylate
This note describes a sequence converting an oxime-substituted pyrrolidine into a trisubstituted pyrrole structure. The synthetic route is based on a double chlorination of the pyrrolidine substrate followed by the base induced formation of both an imine and a nitrile oxide functionality. The latter reacts with an immobilized thiourea to yield an isothiocyanate which upon elimination generates ...
متن کاملEthyl 1-[(2-chloro-1,3-thiazol-5-yl)methyl]-5-methyl-1H-1,2,3-triazole-4-carboxylate
In the title compound, C(10)H(11)ClN(4)O(2)S, the triazole ring carries methyl and ethoxy-carbonyl groups and is bound via a methyl-ene bridge to a chloro-thia-zole unit. There is also evidence for significant electron delocalization in the triazolyl system. Intra- and inter-molecular C-H⋯O hydrogen bonds together with strong π-π stacking inter-actions [centroid-centroid distance 3.620 (1) Å] s...
متن کاملCrystal structure of methyl 5-acetamido-2-t-butyl-2-methyl-1,3-benzodioxole-4-carboxylate.
1,3-benzodioxle-4-carboxylic acid] was designed as a novel class of chiral fluorometric agents.1 The chiral agent and the analogues have been conveniently applied to enantiomer analyses of various bio-molecules using HPLC and circular dichroism.2 We recently extended the molecular design of (S)TBMB carboxylic acid to chiral nitrobenzoic acids possessing the asymmetric 1,3-benzodioxole.3 The chi...
متن کاملMethyl 1-[(Z)-2-(benzyloxycarbonyl)hydrazin-1-ylidene]-5-chloro-2-hydroxyindane-2-carboxylate
The title compound, C19H17ClN2O5, is an important inter-mediate for the synthesis of the pesticide Indoxacarb [systematic name: (S)-methyl 7-chloro-2-{[(meth-oxy-carbon-yl)[4-(tri-fluoro-meth-oxy)phen-yl]amino]-carbon-yl}-2H,3H,4aH,5H-indeno-[1,2-e][1,3,4]oxadiazine-4a-carboxyl-ate] The C=N double bond has a Z conformation. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal structure...
متن کاملsynthesis and antioxidant evaluation of 4-(furan-2-yl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate esters
biginelli-type pyrimidines contain an interesting moiety which has attracted considerable attention of medicinal chemists in the last few decades. despite the very diverse pharmacologic effects ascribed to this kind of pyrimidines, there are few reports on the antioxidant evaluation of biginelli pyrimidines. in this study synthesis of some novel biginelli-type pyrimidines is reported. the prepa...
