Career opportunities within science and technology are seeing unprecedented growth across the world, Quality Control of 3,4-Di(1H-indol-3-yl)-1H-pyrrole-2,5-dione, and those who study chemistry or another natural science at university now have increasingly better career prospects. In an article，Which mentioned a new discovery about 119139-23-0
A synthetic pathway for the synthesis of unit-B of cryptophycin-24 has been developed using Sharpless asymmetric dihydroxylation as the key step. This study shows that direct azidation of alpha-hydroxy acid ester using diphenylphosphoryl azide is beneficial to asymmetric synthesis of alpha-amino acid without the loss of chirality during the transformation.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 119139-23-0.
