With respect to acute toxicity, simple alcohols have low acute toxicities. Doses of several milliliters are tolerated. 72824-04-5, formula is C9H17BO2, For pentanols, hexanols, octanols and longer alcohols, LD50 range from 2–5 g/kg (rats, oral). Ethanol is less acutely toxic.All alcohols are mild skin irritants. Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
Zwillinger, Marton;Reddy, Post Sai;Wicher, Barbara;Mandal, Pradeep K.;Csekei, Marton;Fischer, Lucile;Kotschy, Andras;Huc, Ivan research published 《 Aromatic Foldamer Helices as α-Helix Extended Surface Mimetics》, the research content is summarized as follows. Helically folded aromatic oligoamide foldamers have a size and geometrical parameters very distinct from those of α-helixes and are not obvious candidates for α-helix mimicry. Nevertheless, they offer multiple sites for attaching side chains. It was found that some arrays of side chains at the surface of an aromatic helix make it possible to mimic extended α-helical surfaces. Synthetic methods were developed to produce quinoline monomers suitably functionalized for solid phase synthesis. A dodecamer was prepared Its crystal structure validated the initial design and showed helix bundling involving the α-helix-like interface. These results open up new uses of aromatic helixes to recognize protein surfaces and to program helix bundling in water.
Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, 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.
