Bis-DCM Type Dyes: Convenient Method for Synthesis of 2-(2, 6-bis(4-(dialkylamino)styryl)-4H -pyran-4-ylidene) Malononitrile Derivatives
An efficient and convenient method for synthesis of 2,6-bis (4-(dialkylamino) styryl)-4H-pyran-4-one starting from 4- (dialkylamino) benzaldehyde with 2,6-dimethyl-4H-pyran-4-onein the presence of MeONa as the base was described. Additionally, preparation of novel compounds with bis-DCM-type skeleton for application in organic light-emitting diodes was developed via reactio...
متن کاملFacile synthesis and herbicidal evaluation of 4H-3,1-benzoxazin-4-ones and 3H-quinazolin-4-ones with 2-phenoxymethyl substituents.
Series of 4H-3,1-benzoxazin-4-ones and 3H-quinazolin-4-ones with phenoxy-methyl substituents were rationally designed and easily synthesized via one-pot N-acylation/ring closure reactions of anthranilic acids with 2-phenoxyacetyl chlorides to yield the 4H-3,1-benzoxazin-4-ones, and subsequently substituted with amino derivatives to obtain the 3H-quinazolin-4-ones. The herbicidal evaluation was ...
متن کامل3,5-Dihydroxy-2-methyl-4H-pyran-4-one
In the title compound, C(6)H(6)O(4), inter- and intra-molecular hydrogen bonds are observed which help to establish the crystal structure. There are weak π-π interactions between pyran rings separated by 3.5692 (9) Å.
متن کامل5-Hydroxy-2-methyl-4H-pyran-4-one
The title compound, C(6)H(6)O(3), is a member of the pyrone family. The mol-ecules are planar (r.m.s. deviation of the asymmetric unit is 0.0248 Å, whereas that of the dimer is 0.0360 Å) and they are dimerized due to inter-molecular O-H⋯O hydrogen bonds. The dimers are connected to each other through hydrogen bonds involving the CH(3) group and the hydr-oxy O atom. There are π-π inter-actions b...
متن کاملSynthesis of functionalised 4H-quinolizin-4-ones via tandem Horner-Wadsworth-Emmons olefination/cyclisation.
4H-Quinolizin-4-ones are a unique class of heterocycle with valuable physicochemical properties and which are emerging as key pharmacophores for a range of biological targets. A tandem Horner-Wadsworth-Emmons olefination/cyclisation method has been developed to allow facile access to substituted 4H-quinolizin-4-ones encoded with a range of functional groups.
