Benzaldehyde and its metabolic intermediates were effectively degraded by the brown-rot basidiomycetes Tyromyces palustris and Gloeophyllum trabeum. The pathway of benzaldehyde degradation was elucidated by the identification of fungal metabolites produced upon the addition of benzaldehyde and its metabolic intermediates. The oxidation and reduction occurred simultaneously, forming benzyl alcoh...

Recent investigations have shown the oxone-mediated oxidative methyl esterification of benzaldehyde derivatives using methanol. The reactions were accelerated in the presence of indium(III) triflate, a trivalent indium reagent, in many cases. Based on this method of methyl esterification of benzaldehyde derivatives, we further explored an application to heterocyclic aldehydes. The reactions wer...

2-(6,8-Dibromo-2-methylquinazolin-4-yloxy)-acetohydrazide (4) was prepared by the reaction of 6,8-dibromo-2-methylbenzo-[d][1,3]oxazin-4-one with formamide to afford quinazolinone 2, followed by alkylation with ethyl chloroacetate to give the ester 3. Treatment of ester 3 with hydrazine hydrate and benzaldehyde afforded 4 and styryl quinazoline 5. The hydrazide was reacted with triethyl orthofo...

in this study a special type of silicoaluminophosphate with opal structure (opal-sapo) was prepared under microwave condition using tetraethylorthosilicate (teos), triethanolamine (tea), aluminiumisopropoxid and phosphoric acid 85%. the product was characterized by x-ray diffraction (xrd), thermogravimetric (tga) and fourier infrared spectroscopy (ftir).the crystalline product showed a good act...

functionalized indeno[1,2-b]chromene derivatives have been synthesized via condensation reaction of 1h-indene-1,3(2h)-dione with benzaldehyde and cyclization with 2-hydroxynaphthalene-1,4-dione in the presence of a catalytic amount of triethylamine (et3n) in etoh at room temperature. it was observed that benzaldehyde bearing electron donating group gave high yield of product, whereas, benzaldeh...

The one-pot three-component reaction of 2-aminobenzothiazole, benzaldehyde derivatives and β-ketoester, β-diketone or malonate derivatives in solvent-free conditions provides the corresponding pyrimido[2,1-b]benzothiazole derivatives at 60 ̊C in 60% 72% yields without using any catalyst in an optimistic time.
