Stereoselective synthesis of 1-amino-5-butyl-3-oxo- cyclohexane-1-carboxylic acid derivatives
* corresponding author. e-mail: [email protected] Butyl-substituted 1-amino-3-oxocyclohexane-1-carboxylic acid derivatives have been prepared from 5,5-tethered dienes of (2R)-2,5-dihydro-2-isopropyl-3,6-dimethoxypyrazine in stereoselective synthesis. RCM reactions of the diene afforded a heterospirenone which was the substrate for the conjugated addition reaction with lithium dibutylcuprate. Hydrol...
متن کامل1-Methyl-1H-indazole-3-carboxylic acid
The asymmetric unit of the title compound, C(9)H(8)N(2)O(2), contains two mol-ecules. In the crystal structure, both mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, and a C-H⋯O inter-ation is also seen.
متن کامل2-(2-Chlorophenyl)-5-methyl-1,3-dioxane-5-carboxylic acid
In the title compound, C(12)H(13)ClO(4), the 1,3-dioxane ring adopts a chair conformation and the 2-chloro-benzene and methyl substituents occupy equatorial sites. The carboxyl group is in an axial inclination. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
متن کامل4-Methyl-2-n-propyl-1H-benzimidazole-6-carboxylic acid
In the title compound, C(12)H(14)N(2)O(2), the benzene ring and imidazole ring are almost coplanar, making a dihedral angle of 2.47 (14)°. Inter-molecular O-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds stabilize the crystal structure.
متن کامل5-Methyl-1-phenyl-1H-1,2,3-triazole-4-carboxylic acid
The title compound, C(10)H(9)N(3)O(2), was synthesized from azido-benzene and ethyl acetyl-acetate. A pair of hydrogen bonds [2.617 (2) Å] inter-connects a pair of the carboxyl groups, forming an R(2) (2)(8) inversion dimer, a frequent motif in carboxylic acids. In the title structure, the bonding H atom in the aforementioned O-H⋯O hydrogen bond is significantly shifted towards the acceptor O a...
