Recommanded Product: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. 72824-04-5, name is 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, An important class of alcohols, of which methanol and ethanol are the simplest examples, includes all compounds which conform to the general formula CnH2n+1OH.
Sharma, Hayden A.;Essman, Jake Z.;Jacobsen, Eric N. research published 《 Enantioselective catalytic 1,2-boronate rearrangements》, the research content is summarized as follows. A strategy that facilitates the construction of a wide variety of trisubstituted stereocenters through a catalytically accessed common chiral intermediate could prove highly enabling for the field of synthetic chem. The authors report the discovery of enantioselective, catalytic 1,2-boronate rearrangements for the synthesis of α-chloro pinacol boronic esters from readily available boronic esters and CH2Cl2. The chiral building blocks produced in these reactions can undergo two sequential stereospecific elaborations to generate a wide assortment of trisubstituted stereocenters. The enantioselective reaction is catalyzed by a Li-isothiourea-boronate complex, which is proposed to promote rearrangement through a dual-Li-induced chloride abstraction orchestrated by Lewis basic functionality on the catalyst scaffold.
72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., Recommanded Product: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
