Industrial preparation method of 3,5-dimethoxy-4-alkylbenzyl alcohol

The invention discloses an industrial preparation method of 3,5-dimethoxy-4-alkylbenzyl alcohol, belonging to the technical field of organic synthesis. According to the method, isopropyl chloride or isopropyl alcohol p-toluenesulfonate is selected, and isopropyl alcohol p-toluenesulfonate is directly subjected to Friedel-Crafts alkylation under the action of triethylamine hydrochloride ionic liquid serving as both a solvent and a catalyst; after the above reaction is finished, an organic solvent, such as methyl tert-butyl ether, is used for direct extraction and liquid separation, and the ionic liquid can be used repeatedly; sodium borohydride is directly used for reducing acyl imidazole obtained by subjecting isopropyl ester obtained in the previous stepto exchanging with imidazole in an aqueous tetrahydrofuran solution mildly (under the condition of 0-30 DEG C and without adding a catalyst); and after reduction is completed, a reduction product is directly poured into strong alkali solution with a concentration of 1-6 mol/L for quenching, and an organic phase is separated, so the 3,5-dimethoxy-4-alkylbenzyl alcohol is obtained safely and environmentally. The method is convenient and safe to operate, greatly reduces the problem of environmental pollution, and is suitable for industrial production.

Efficient synthesis of sterically hindered arenes bearing acyclic secondary alkyl groups by suzuki-miyaura cross-couplings

Bulky P,P-O ligands were designed to inhibit isomerization and reduction side reactions during the cross coupling between sterically hindered aryl halides and alkylboronic acids. Suzuki-Miyaura cross-couplings between di-ortho-substituted aryl bromides and acyclic secondary alkylboronic acids have been achieved with high yields. The method has also enabled the preparation of ortho-alkoxy di-ortho-substituted arenes bearing isopropyl groups in excellent yields. The utility of the synthetic method has been demonstrated in a late-stage modification of estrone and in the application to a new synthetic route toward gossypol. No side reaction: The shown bulky P,P-O ligands (right) successfully inhibit isomerization and reduction side reactions of the cross-coupling of sterically hindered substrates such as di-ortho-substituted aryl bromides with acyclic secondary alkylboronic acids. The method also allows the preparation of ortho-alkoxy di-ortho-substituted isopropyl arenes in excellent yields.

Total synthesis of (±)-komaroviquinone

(±)-Komaroviquinone (1) was synthesized from 3,4,5-trimethoxybenzoic acid in twenty-two steps. The key transformations in this synthesis are: (1) the construction of the cycloheptane ring via a Friedel-Crafts cyclialkylation; (2) a regiospecific benzylic oxidation; (3) a conformationally controlled introduction of the C(10) hydroxyl group and (4) intramolecular hemi-acetal formation.

Total synthesis of (±)-Taiwaniaquinol B via a domino intramolecular Friedel-Crafts acylation/carbonyl α-tert-alkylation reaction

The first synthesis of taiwaniaquinol B, a 6-nor-5(6→7)abeoabietane-type diterpenoid exhibiting the uncommon fused 6-5-6 tricyclic carbon skeleton, was accomplished in 15 steps. A Lewis acid-promoted tandem intramolecular Friedel-Crafts/carbonyl α-tert-alkylation reaction was exploited as the core strategy for the synthesis of the sterically congested 1-indanone-containing tricyclic structure. This multiple carbon-carbon bond forming reaction exploits the unique reactivity of Meldrum's acid. The facile precursor synthesis makes this a useful methodology for the expedient modification and assembly of sterically congested 1-indanone-containing ring systems. Copyright
