The author of 《Fluorinated iminophosphonates bearing stereodirecting phenylethyl group in synthesis of biorelevant scalemic aminophosphonates》 were Stanko, Oleg V.; Rassukana, Yuliya V.; Onys’ko, Petro P.. And the article was published in Phosphorus, Sulfur and Silicon and the Related Elements in 2019. Recommanded Product: 2,5-Dimethoxytetrahydrofuran The author mentioned the following in the article:
Diastereoselective reduction of α-(poly)fluoroalkylated iminophosphonates, bearing stereodirecting phenylethyl group at the nitrogen atom, produces diastereomeric N-(α-phenylethyl) polyfluoroalkylphosphonates. Separation and N-deprotection affords (S) and (R) α-amino polyfluoroalkylphosphonates. The latter react with 2,5-dimethoxytetrahydrofuran to give optically pure polyfluoroalkylphosphonates incorporating 1-pyrrolyl group in α-position. The results came from multiple reactions, including the reaction of 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Recommanded Product: 2,5-Dimethoxytetrahydrofuran)
2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. Friedel Crafts reaction, for example, adds an alkyl or acyl group to aromatic ethers when they react with an alkyl or acyl halide in the presence of a Lewis acid as a catalyst.Recommanded Product: 2,5-Dimethoxytetrahydrofuran
