Ibrahim, Dhuaou; Boulet, Pascal; Gros, Philippe C.; Pierrat, Philippe published their research in European Journal of Organic Chemistry in 2021. The article was titled 《Efficient Access to Arylated Aza-ullazines by Regioselective Functionalization of their Pyridine Ring by H-Li Exchange and Electrophilic Substitution》.Application of 696-59-3 The article contains the following contents:
The regioselective functionalization of aza-ullazines had been successfully realized for the first time by either metalation using BuLi-containing aggregates (BuLi-LiDMAE) or electrophilic substitution. Mono and di-bromo-derivatives were obtained in good to excellent yields and further successfully converted into aryl-azaullazines I [R = H, Ph; Ar = Ph, 4-CHOC6H4, 6-chloro-3-pyridyl, 5-formyl-2-thienyl] and alkynyl-azaullazines II [R1 = H, CCPh; Ar1 = Ph, 4-Bu2NC6H4] by Suzuki and Sonogashira cross-coupling reactions. The experimental part of the paper was very detailed, including the reaction process of 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Application of 696-59-3)
2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. When aromatic ethers are exposed to halogen in the presence or absence of a catalyst, they undergo halogenation, such as bromination.Application of 696-59-3
