Synthesis method for raw material drugs of dicamba

The invention relates to a synthesis method for raw material drugs of dicamba. The synthesis method for the raw material drugs of dicamba comprises the following steps: taking 2,5-dichlorophenol as a starting material, carrying out esterification under the actions of an organic solvent and an organic esterification reagent to generate 2,5-dichlorophenol acetate; dissolving 2,5-dichlorophenol acetate in the organic solvent and adding a catalyst to generate Fries rearrangement, thus generating 3,6-dichloro-2-hydroxyacetophenone; making 3,6-dichloro-2-hydroxyacetophenone react with a methylating reagent under the action of an acid-binding agent to obtain 3,6-dichloro-2-methylacetophenone; synthesizing dicamba (3,6-dichloro-2-methoxybenzoic acid) under the action of 3,6-dichloro-2-methylacetophenone. The synthesis method for the raw material drugs of dicamba disclosed by the invention is simple in process, highly available in raw materials and the catalyst, low in cost, simple in post-treatment operation, low in environmental pollution, high in safety of reaction operation, high in reaction yield, good in product quality and favorable for industrialization.

Carbohydrate rod conjugates: Ternary rod-coil molecules forming complex liquid crystal structures

T-shaped polyphilic triblock molecules, consisting of a rodlike p-terphenyl unit, a hydrophilic and flexible laterally attached oligo(oxyethylene) chain terminated by an 1-acylamino-1-deoxy-D-sorbitol unit, and two end-attached lipophilic alkyl chains, have been synthesized by palladium-catalyzed cross-coupling reactions as the key steps. The thermotropic liquid crystalline behavior of these compounds was investigated by polarized light microscopy, differential scanning calorimetry (DSC), and X-ray scattering. We investigated the mode of self-organization as a function of the length and position of the lateral polar chain and the length of the terminal alkyl chains. Depending on the size of the polar and lipophilic segments, a series of unusual liquid crystalline phases was detected. In three of these phases, the space is divided into three distinct periodic subspaces. In addition to a hexagonal channeled layer phase (ChLhex) consisting of layers that are penetrated by polar columns, there are also two honeycomb-like network structures formed by square (Colsqu/p4mm) or pentagonal cylinders (Colsqu/p4gm) . The cylinder walls consist of the terphenyl units fused by columns of alkyl chains, and the interior contains the polar side chains. In addition, a hexagonal columnar phase was observed in which the polar columns are organized in a continuum of terphenyls and alkyl chains with an organization of the terphenyl cores tangentially around the columns with the long axis perpendicular to the columns. For one compound, a reversal of birefringence was observed, which is explained by a reorientation of the terphenyl cores. The addition of protic solvents induces lamellar phases.
