A novel use of Boc-Oxyma as reagent for tert-butoxycarbonylation of amines and amino acid esters was written by Robert, Alice R.;Kumar, Ganta Ravi;Kumar, Thoota Sandeep;Maddila, Suresh;Jonnalagadda, Sreekantha B.. And the article was included in Chemical Data Collections in 2020.HPLC of Formula: 185619-66-3 This article mentions the following:
A facile and suitable approach has been improved to protect various amines, including sterically hindered amino acid esters, as their carbamates using Boc-Oxyma in the presence of triethylamine as a base catalyst in neat or solvent medium at room temperature A significant advantage of this protocol is easy handling, short reaction times, simple workup process, TEA as solvent plus catalyst under mild conditions, avoiding column chromatog. for purification technique and excellent product yields. In the experiment, the researchers used many compounds, for example, tert-Butyl (3-ethynylphenyl)carbamate (cas: 185619-66-3HPLC of Formula: 185619-66-3).
tert-Butyl (3-ethynylphenyl)carbamate (cas: 185619-66-3) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.HPLC of Formula: 185619-66-3
