2-Amino-4-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile
In the title compound, C(10)H(12)N(2)S, the thio-phene ring is essentially planar (r.m.s. deviation = 0.0290 Å). The two C atoms of the cyclo-hexene ring (at positions 6 and 7) are disordered over two sets of sites in a 0.810 (5):0.190 (5) ratio. The cyclo-hexene rings in both the major and minor occupancy conformers adopt a half-chair conformation. In the crystal, there are two types of N-H⋯N ...
متن کامل(±)-Methyl 1,1a,2,7b-Tetrahydro-2-oxocyclopropa[c] Chromene-1a-carboxylate
A novel method for the preparation of (±)-methyl 1,1a,2,7b-tetrahydro-2-oxocyclopropa[c] chromene-1a-carboxylate has been developed. The cyclopropanation of methyl coumarin-3-carboxylate provided title compound in moderate yield by dropwise treatment with 1.5 equiv. of dimethylsulfoxonium methylide over 6 h. The structure of the newly synthesized compound was determined using 1H-, 13C-NMR, IR a...
متن کاملMethyl 3-(Quinolin-2-yl)indolizine-1-carboxylate
A novel compound, methyl 3-(quinolin-2-yl)indolizine-1-carboxylate (2) has been synthesized by cycloaddition reaction of 1-(quinolin-2-ylmethyl)pyridinium ylide (1) with methyl propiolate in presence of sodium hydride in THF. The structure of this compound was established by IR, 1H-NMR, 13C-NMR and MS data.
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 کامل3-Hydroxypyridinium-2-carboxylate
Comparable to many amino acids, the title compound, C(6)H(5)NO(3), is a substitution product of picolinic acid. The mol-ecule shows approximate non-crystallographic C(s) symmetry. Like many amino acids, the mol-ecule is present in its zwitterionic state. Intra- as well as inter-molecular hydrogen bonds are observed, the latter connecting the mol-ecules into zigzag chains along the crystallograp...
