Synthesis method of atropine and atropine sulfate

The invention provides a synthesis method of atropine and atropine sulfate, which comprises the following steps: carrying out acetylation reaction on tropine acid to form acetyl tropine acid, reactingthe acetyl tropine acid with a chlorination reagent to form acyl chloride, reacting the acyl chloride with tropine alcohol, removing acetyl to obtain atropine, and salifying atropine and sulfuric acid to obtain atropine sulfate. The whole synthesis process can be completed by adopting a one-pot reaction, additional steps for completing the process by isolating intermediates are avoided, the reaction conditions are mild, the steps are simple, the yield is high, the purity is high, and the method is suitable for large-scale industrial production.

PhSO2SCF2H: A Shelf-Stable, Easily Scalable Reagent for Radical Difluoromethylthiolation

A new shelf-stable and easily scalable difluoromethylthiolating reagent S-(difluoromethyl) benzenesulfonothioate (PhSO2SCF2H) was developed. PhSO2SCF2H is a powerful reagent for radical difluoromethylthiolation of aryl and alkyl boronic acids, decarboxylative difluoromethylthiolation of aliphatic acids, and a phenylsulfonyl-difluoromethylthio difunctionalization of alkenes under mild reaction conditions.
