SYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID
Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...

متن کاملThe Synthesis of 2, 6 diamino- 3, 5-dinitropyridine from Direct Nitration Reaction of 2, 6 diamino pyridine in Different Temperature Conditions by Density Functional Theory
In this article, synthesis of the explosive 2, 6 (diamino) 3, 5 dinitro pyridine (ANPY) of the direct nitration reaction of 2, 6 diamino pyridine in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then the calculation of the the...
متن کامل6-Nicotinamido-2-naphthoic acid
In the title mol-ecule, C(17)H(12)N(2)O(3), the naphthalene ring system and the pyridin-3-yl rings are nearly coplanar with a dihedral angle between them of 2.28 (8)°. In the crystal, the hy-droxy and amide N atoms participate in hydrogen bonds, which connect the mol-ecules into a two-dimensional network parallel to (101).
متن کامل2-Methoxycarbonyl-6-nitrobenzoic acid
In the title compound, C(9)H(7)NO(6), the dihedral angles between the benzene ring and its three substituents are 29.99 (8)° for the nitro, 67.09 (8)° for the carb-oxy and 32.48 (10)° for the meth-oxy-carbonyl group. In the crystal, one classical O-H⋯O and two nonclassical C-H⋯O contacts link adjacent mol-ecules, forming a three-dimensional structure.
