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
Wang, Min;Liu, Xiao;Wang, Liying;Lu, Haifeng;Gao, Hongyin research published 《 Cooperative Gold/Zinc-catalyzed Cascade Approach to Tryptophan Derivatives from N-arylhydroxylamines and Alkynes》, the research content is summarized as follows. A cooperative gold/zinc catalyzed strategy for the synthesis of tryptophan derivatives from easily prepared N-arylhydroxylamines and chiral amino acid tethered alkynes with high efficiency has been developed. The structurally diverse tryptophan derivatives including pharmaceutical relevant mols. can be readily prepared by this method. This tandem transformation starts from acyclic simple materials rather than the existing methods by modifying indole skeletons.
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., Name: 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
