Dill and parsley seed extracts in scale up synthesis of aminopolyalkoxybenzenes – beneficial synthons for fused nitrogen polyalkoxyheterocycles

Ecologically friendly transformation of readily accessible plant allylpolyalkoxybenzenes to hardly available aminotetraalkoxybenzenes has been developed. The efficacy of hydrogenation stage is substantially increased by the application of highly porous ceramic block Pd-catalysts featuring a large surface area, low hydraulic resistance, significant thermal and mechanical stabililty, multiple cycling and easy regeneration.
