Electric Literature of 72824-04-5, 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.
Liu, Xiang-Shuai;Li, Yao;Li, Xin research published 《 Bi(OAc)3/Chiral Phosphoric Acid-Catalyzed Enantioselective 1,2- and Formal 1,4-Allylation Reaction of β,γ-Unsaturated α-Ketoesters》, the research content is summarized as follows. A highly efficient asym. 1,2-allylation reaction of β,γ-unsaturated α-ketoesters (E)-R1CH:CHC(O)C(O)OR2 (R1 = Ph, thiophen-2-yl, naphthalen-2-yl, etc.; R2 = Et, Bn, cyclohexyl, etc.) was realized by using a Bi(OAc)3/chiral phosphoric acid catalyst system under mild conditions. Meanwhile, using this combined strategy of enantioselective 1,2-allylation and subsequent anionic oxy-Cope rearrangement, the asym. formal 1,4-allylation reaction was achieved by a one-pot process. These reactions offer rapid access to an array of homoallylic tertiary alcs. (S)/(R)/(E)-R1CH:CHC(OH)C(O)OR2CH2CH:CH2 and γ-allyl-α-ketoesters (S)-R1C(OH)C(O)OR2CH2CH:CH2 with good yields and excellent enantioselectivities. D. functional theory calculations were conducted to interpret the high enantioselectivity.
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., Electric Literature of 72824-04-5
