Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 57-48-7, Name is (3S,4R,5R)-1,3,4,5,6-Pentahydroxyhexan-2-one, molecular formula is C6H12O6. In an article, author is Qin, Shuanglin,once mentioned of 57-48-7, Category: chiral-catalyst.
A one-step catalytic and diastereoselective method for the synthesis of aziridines possessing multiple chiral substitutions by radical aminotrifluoromethylation of alkenes has been developed for the first time. The reaction utilizes a Cu(I)/L-proline complex as a catalyst and a chiral sulfinamide group performs the role of nucleophile and chiral directing group. This synthetic strategy provides one-step access to a wide variety of substituted aziridines with good chemical yield, excellent diastereoselectivity and broad functional group tolerance. A possible reaction mechanism is proposed based on DFT calculations. The method should be useful for the rapid synthesis of chiral CF3-containing building blocks and novel drug molecules.
