Synthesis and antifungal activity of 5-chloro-6-phenylpyridazin-3(2H)-one derivatives.
An effective method has been developed for the preparation under mild conditions of novel pyridazine derivatives from the easily accessible starting materials mucochloric acid and benzene. All the synthesized compounds were fully characterized and some of them displayed good antifungal activities against G. zeae, F. oxysporum and C. mandshurica in preliminary antifungal activity tests.
متن کامل6-Chloroquinolin-2(1H)-one
In the title compound, C(9)H(6)ClNO, the Cl atom deviates by 0.142 (1) Å from the quinoline ring mean plane (r.m.s. deviation = 0.013 Å). In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into [010] C(4) chains. Aromatic π-π stacking inter-actions [shortest centroid⋯centroid distance = 3.685 (3) Å] are also observed.
متن کاملSynthesis of benzyl esters using 2-benzyloxy-1-methylpyridinium triflate.
Triethylamine (Et3N) mediates esterification reactions between the title reagent (1) and carboxylic acids. Alcohols, phenols, amides, and other sensitive functionality are not affected; a dual role for Et3N as a promoter and a scavenger is postulated. Benzyl esters are obtained from substrates including amino acid and sugar derivatives.
متن کامل2-Benzyl-6-benzyloxypyridazin-3(2H)-one
In the title compound, C(18)H(16)N(2)O(2), the central pyridazine ring forms dihedral angles of 77.08 (5)° and 84.62 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 68.18 (4)°. A very weak intra-molecular C-H⋯N hydrogen bond and an intra-molecular C-H⋯π inter-action occur. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds and w...
متن کامل2-(4-Chlorophenyl)-6-methoxychroman-4-one
In the title mol-ecule, C(16)H(13)Cl O(3), the two aromatic rings form a dihedral angle of 65.3 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed into columns propagating in [100] by weak C-H⋯π inter-actions.
