In 2022,Kondoh, Azusa; Hirozane, Takayuki; Terada, Masahiro published an article in Chemistry – A European Journal. The title of the article was 《Formal umpolung addition of phosphites to 2-azaaryl Ketones under chiral Broensted base catalysis: enantioselective protonation utilizing [1,2]-phospha-Brook rearrangement》.Product Details of 2398-37-0 The author mentioned the following in the article:
The formal enantioselective umpolung addition of dialkyl phosphites to 2-azaaryl ketones was developed under Broensted base catalysis. The reaction involved the enantioselective protonation of the transient α-oxygenated (2-azaaryl)methyl anion generated through the 1,2-addition of the anion of dialkyl phosphite to the 2-azaaryl ketone and the subsequent [1,2]-phospha-Brook rearrangement. A chiral bis(guanidino)iminophosphorane organosuperbase efficiently catalyzed the reaction to provide enantio-enriched phosphates in high yields with good to high enantioselectivities. This is a rare example of the catalytic enantioselective protonation of transient carbanions other than enolates, constructing a trisubstituted stereogenic center α to 2-azaarenes. After reading the article, we found that the author used 1-Bromo-3-methoxybenzene(cas: 2398-37-0Product Details of 2398-37-0)
