Synthetic Route of 2186-92-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2186-92-7, name is P-anisaldehyde dimethyl acetal belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
2) Synthesis of [6-Methoxy-3,4,5-Tris(4-Methoxy-Benzyloxy)Tetrahydropyran-2-yl]Methanol of Formula (V)a) Step 1: Synthesis of 6-methoxy-2-(4-methoxyphenyl)-hexahydropyrano[3,2-D][1,3]dioxine-7,8-diol of formula (VII)The synthesis begins with the protection of the primary alcohol (VIII) (3,4,5-trihydroxy-6-methoxytetrahydro-pyran-2-ylmethanol) in the form of an acetal (VII) (6-methoxy-2-(4-methoxyphenyl)hexahydropyrano[3,2-D]-[1,3]dioxine-7,8-diol) through the action of p-anisaldehyde dimethyl acetal (III) in the presence of camphorsulfonic acid in DMF (dimethylformamide).The reaction is carried out at ambient temperature under an industrial vacuum (pressure=40 mbar) (evaporation of the methanol form) for 2 hours, so that a significant advancement in the formation of the desired product is observed, such that only traces of the starting product remain.After an aqueous treatment in a basic medium, the traces of starting product are eliminated by washing with cyclohexane; this makes it possible to isolate the compound (VII) in the form of a white solid with yields of between 60% and 80%
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, P-anisaldehyde dimethyl acetal, other downstream synthetic routes, hurry up and to see.
