Paragraph 0009; 0010, (2019/05/16)
The invention belongs to the field of organic matter synthesis, and particularly relates to an irsogladine maleate preparation method, wherein p-dichlorobenzene is used as a starting raw material, andfive reactions of acetylation, bromoform reaction, cyanation, cyclization and salt formation are performed to prepare the target compound. According to the present invention, the new irsogladine maleate preparation method is used, can significantly accelerate the reaction rate and improve the yield, has advantages of cost reducing, environment protection, simple operation and convenient post-treatment, and is suitable for industrial production.

A practical one-pot synthesis of chiral alcohols from readily available alkynes via tandem catalysis by the combination of CF3SO3H and a fluorinated chiral diamine Ru(ii) complex in aqueous CF3CH2OH is described. Very interestingly, the combination of fluorinated catalysts and solvent exhibits a positive fluorine effect on the reactivity and enantioselectivity. A range of chiral alcohols with wide functional group tolerance was obtained in high yield and excellent stereoselectivity under simple and mild conditions.

The treatment of α-haloketones with 1.5 equiv. of Zn and 1 equiv. of NH4Cl in ethanol for 0.5αmin gave the corresponding ketones with excellent yields under microwave irradiation. Vic-dibromides and 2,2-dibromoacetophenone can be efficiently debrominated to alkenes and acetophenones, respectively. Copyright Taylor & Francis Group, LLC.
