Palladium-catalysed reactions of conjugated enyne oxiranes with organoborons: A diastereoselective method of the synthesis of 2,4,5-trienol derivatives

A palladium-catalysed reaction of conjugated enyne oxiranes with organoboron reagents is described. This method allows aryl-substituted vinylallenes containing a hydroxyl group on the allylic position to be synthesized, with good diastereomeric ratios, un

Economical and Readily Accessible Preparation of o,o-Disubstituted Arylboronates through Palladium-Catalyzed Borylation of Haloarenes

Miyaura borylation, that is, palladium-catalyzed cross-coupling between bromoarenes and diboron, offers a versatile method for preparing arylboronates; however, a costly and inaccessible catalyst has been required for synthesizing highly congested arylboronates with the method. Here the Pd(OAc)2–tri(4-methoxyphenyl)phosphine catalyst was found to work as an efficient catalyst for the sterically demanding borylation. A broad range of o,o-disubstituted bromoarenes were converted into the corresponding arylboronates in high yields by using the palladium catalyst with Cs2CO3 in EtOAc at 80 °C.

The steric aryl boric acid ester preparation method of the compound

The invention discloses a preparation method of a high-sterically-hindered arylborate compound. The preparation method includes following steps: in the presence of a catalyst of a catalyst tri(dibenzalacetone)dipalladium with a phosphine ligand (wherein the phosphine ligand is 3-diphenylphosphine-2-(2,6-dimethoxylphenyl)-N-methylindole), adding an aryl chloride, bis(neopentyl glycolato)diboron, and an additive ceseium acetate to a 1,4-dioxane solution; and carrying out a reaction at 100-130 DEG C for 12-48 hours to obtain the arylborate compound. In the invention, the employed substrate is stable, is low in cost and is easy to obtain and the catalyst is unique, is easy to prepare and is suitable for the reaction of the high-sterically-hindered aryl chloride. The system is compatible of existences of functional groups, such as an ester group, an aldehyde group, methoxyl and the like so that range of the substrate is greatly developed. The catalyst system is stable, is high in catalytic activity, is wide in suitable scope, is good in selectivity and is mild in reaction conditions. The high-sterically-hindered arylborate compound can be widely applied in cross coupling reaction catalyzed by transition metal, thereby preparing various compounds, such as biaromatic hydrocarbons. The preparation method has a great application potential in synthesis of natural medicines and drug intermediates.
