Ionic liquid catalytic synthesis of styrene-acrylic acid ester derivative of the method (by machine translation)

The invention provides an ionic liquid catalytic synthesis of styrene-acrylic acid ester derivative of the method, the method adopts the imidazole ionic liquid as catalyst, in order to cinnamic aldehyde or its derivatives and nandrolone or testosterone alcohol or phenol derivatives as raw materials, without any additional acid and alkali, one-step reaction, to obtain the styrene-acrylic acid ester derivative. Compared with the prior art, the maximum of this invention is characterized in that the raw materials are all simple and easy to obtain, security and stability of the compound, the reaction time is short, after the reaction by simple extraction, concentration or crystallization can be obtained pure product, at the same time can also be realized in the use of the recycling of the catalyst, catalyst recycled is very convenient and almost no "wastes" problem. The invention it has less catalyst levels, the reaction selectivity is high, and the yield is high, the operation is simple, pollution is small, green high degree of several advantages; in the setting under the reaction conditions, the conversion of raw materials and the yield of the product are as high as 90% or more.

A New and Efficient Method for the Preparation of S-Phenyl Carbothioates via Mixed Anhydrides Using Active Titanium(IV) Salts

In the presence of a catalytic amount of titanium(IV) salt, various S-phenyl carbothioates are prepared in excallent yields by the reaction of nearly equimolar amounts of silyl derivatives of carboxylic acids and benzenethiols with p-trifluoromethylbenzoic anhydride.

APPLICATION OF THE PHOTO-FRIES REARRANGEMENT OF ARYL DIHYDROCINNAMATES TO THE SYNTHESIS OF FLAVONOIDS

The photo-Fries rearrangement of aryl dihydrocinnamates is compared with that of the analogous cinnamates from a preparative point of view.The former proceeds with higher conversions, giving the corresponding 2'-hydroxydihydrochalcones in acceptable yields.This process, combined with well established reactions, provides an alternative entry to the synthesis of flavonoids.
