What is P-ANISALDEHYDE DIMETHYL ACETAL?

Chemical properties

clear colorless to light yellow liquid

The Uses of P-ANISALDEHYDE DIMETHYL ACETAL

4-Methoxybenzaldehyde dimethyl acetal is used as a precursor to 1-methoxy-1-(4-methoxyphenyl)hept-2-yne, 2,5-dioxopyrrolidin-1-yl-3-((4R)-2-(4-methoxyphenyl)-5,5-dimethyl-1,3-dioxane-4-carboxamido)propanoate and 1-(p-anisyl)-2-(2-methoxyethyl)-3-phenylindene. Further, it acts as a protecting group reagent for diols, especially in carbohydrates. It is also used as a flavor essence in sunflower, cyclamen and in jasmine. In addition to this, it is involved in allylation reactions with allyltrimethylsilane catalyzed by Iron(III) chloride.

What are the applications of Application

Anisaldehyde dimethyl acetal is a protecting group reagent for diols

Synthesis

P-Anisaldehyde diMethyl acetal is produced from Anisaldehyde and Methyl alcohol.
