Synthesis and phytotoxic activity of new pyridones derived from 4-hydroxy-6-methylpyridin-2(1H)-one.
Commercial dehydroacetic acid was converted into 4-hydroxy-6-methylpyridin-2(1H)-one (3), which was then condensed with several aliphatic aldehydes to produce seven new title compounds in variable yields (35-92%). Reaction of 3 with alpha,beta-unsaturated aldehydes resulted in the formation of condensed pyran derivatives 4g' and 4h'. A mechanism is proposed to explain the formation of such comp...

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 کامل6-Bromopyridine-2-carboxamide
In the the title compound, C(6)H(5)BrN(2)O, an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring. In the crystal structure, inter-molecular bifurcated N-H⋯(O,O) hydrogen bonds link the mol-ecules, leading to sheets propagating in (100).
متن کاملN′-[(E)-2-Chlorobenzylidene]-2-(6-methoxynaphthalen-2-yl)propanohydrazide
In the title compound, C21H19ClN2O2, the benzene ring and the naphthalene ring system are oriented at a dihedral angle of 65.24 (10)°. In the crystal, N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules, forming chains along the b-axis direction. Further C-H⋯O hydrogen bonds link the chains, forming corrugated sheets lying parallel to (10-1).
متن کامل1-[6-(6-Acetylpyridin-2-yl)pyridin-2-yl]ethanone
In the title compound, C(14)H(12)N(2)O(2), the asymmetric unit comprises one half-mol-ecule with an inversion center between the pyridine rings. The rings are trans coplanar with the acetyl groups deviating slightly from the mean planes, making a dihedral angle of 4.63 (4)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, forming a supra-molecular sheet paral...
