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.

ISOMERISATION OF ο-ALKENYL SUBSTITUTED CYCLOHEXANE-1,3-DIONE ENOL DERIVATES USING RHODIUM CATALYSIS. A PRACTICAL SYNTHESIS OF SUBSTITUTED RESORCINOLS

Treatment of the ο-alkenyl substituted cyclohexane-1,3-dione enol derivates (1), (11), and (13) with rhodium trichloride trihydrate leads to the corresponding resorcinol derivates (2), (12), and (15) respectively.By contrast, the RhCl3.3H2O catalysed isomerisations of the related enol ethers (5) and (9) instead produce the dienones (6) and (10) respectively.
