A PROCESS FOR THE PREPARATION OF VANILLIN AND OTHER SUBSTITUTED PHENYLALDEHYDES
-
Paragraph 0088; 0090, (2022/01/12)
The present invention relates to a chemical process for the production of substituted phenylaldehydes such as vanillin (1a) from substituted phenylpropenes or substituted phenylpropenes enriched essential oils such as eugenol (2a) or eugenol rich essential oils indiscriminately through either cis or trans or a mixture of cis and trans isomer(s) of substituted phenylprop-2-enes such as isoeugenol, an intermediate compound. The invention relates to the conversion of substituted phenylpropenes to other substituted phenylaldehydes, particularly vanillin without the protection of the phenolic group, therefore, it offers a step economy. The present chemical process involves the use of class 3 and 4 solvents thereby devoid of the use of any chlorinated solvent.
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.

Glaziovianin A and its analogues were synthesized in six steps starting from allylpolyalkoxybenzenes separated from essential oils of dill (Anetum graviolens) and parsley (Petro-selinum sativum) seeds.
