Primulin derivative as well as synthesis method and application of primulin derivative

The invention discloses a primulin derivative with antibacterial activity shown as the structural general formula (I), wherein R is selected from C2-C20 alkyls. The primulin derivative is prepared from raw materials including m-dihydroxybenzene and a fatty acid derivative by the steps: carrying out Friedel-Crafts acylation and methylation to synthesize a paeonol derivative, and carrying out oxidization after carrying out carbonyl reduction. The primulin derivative has good antibacterial activity and can be used as a potential antibacterial agent.

Synthese von 4-Alkoxy-2-hydroxyphenylketoximen als Metallextraktions-Reagenzien

The C-Acylation (Friedel-Crafts reaction) of resorcinol with aluminium chloride, the monoetherification in 4-position of the resulting 2,4-dihydroxyphenylketones, and the preparation of oximes (8, 9, 10, 11) from this ketones were investigated.The compounds obtained are characterized by elemental analysis, and the i.r., u.v. and 1H-n.m.r. spectra are discussed.Solubility data of some oximes are determined in water, octane and toluene.The extraction properties for copper-(II)-and iron-(III)-ions are measured by isotope methods in relation to the extragent structure, the extraction time and the pH-range.
