Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 72824-04-5, formula is C9H17BO2, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Category: alcohols-buliding-blocks
Chevis, Philip J.;Promchai, Thanika;Richardson, Christopher;Limtharakul, Thunwadee;Pyne, Stephen G. research published 《 Synthesis of syn- and enantioenriched anti-β-amino alcohols by highly diastereoselective borono-Mannich allylation reactions》, the research content is summarized as follows. A highly diastereoselective method for the synthesis of syn-β-amino alcs. and enantioenriched anti-β-amino alcs. was developed involving α-hydroxyl aldehydes and chiral α-phenylaminoxyaldehydes or α-benzoyloxyaldehydes, resp. in Petasis borono-Mannich allylation reactions. This study broadened the scope and utility of the Petasis reaction to include pinacol allylboronate and highlights its unique reactivity and stereochem. outcomes.
Category: alcohols-buliding-blocks, 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., 72824-04-5.
