Nickel(0)-catalyzed linear-selective hydroarylation of unactivated alkenes and styrenes with aryl boronic acids

Herein, we describe the first linear-selective hydroarylation reaction of unactivated alkenes and styrenes with aryl boronic acids, which was achieved by introducing a directing group on the alkenes. This efficient, scalable reaction serves as a method for modular assembly of structurally diverse alkyl arenes, including γ-aryl butyric acid derivatives, which are widely utilized as chemical building blocks for the synthesis of various drugs and other biologically active compounds.

Two-Step Protocol for Iodotrimethylsilane-Mediated Deoxy-Functionalization of Alcohols

We have developed a two-step protocol for iodotrimethylsilane-mediated deoxy-functionalization of primary and secondary alcohols to afford products containing a C?N, C?S, or C?O bond. In the first step the alcohol undergoes iodination with iodotrimethylsilane, and in the second, the iodine atom is replaced by a N, S, or O nucleophile. Compared with traditional Mitsunobu reaction, non-acidic pre-nucleophiles can be used, and the reaction proceeds with retention of configuration. This operationally simple, highly efficient protocol can be used for some natural products and small-molecule drugs containing hydroxy-group.

A method for one-step synthesis of carboxylic acids with two extended carbon chains from olefins

The invention relates to a method for one-step synthesis of carboxylic acid with two extended carbon chains from olefin, which comprises the following steps: under the protection of inert gas, sequentially adding an olefin substrate, a photocatalyst, a hydrogen atom transfer reagent, alpha-haloacetic acid, a reducing agent, a solvent and protonic acid into a reactor, and reacting at normal temperature under the irradiation of 25W blue light to obtain a reaction product; diluting, alkalizing, washing, acidifying and extracting the reaction product to obtain an organic phase; and finally, carrying out reduced pressure distillation and column chromatography on the organic phase to obtain a carboxylic acid product with two extended carbon chains; or carrying out reduced pressure distillation and column chromatography on the reaction product to obtain a carboxylic acid product with two extended carbon chains. The invention is simple to operate, direct synthesis conditions are mild, mutual conversion among various functional groups in the traditional carboxylic acid compound synthesis process is avoided, and the atom and step economy of the reaction is improved. Meanwhile, the method disclosed by the invention can also be applied to the simplified synthesis of the medicines cinacarbazide and tirofiban.
