In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Asymmetric catalytic Strecker reaction of N-phosphonyl imines with Et2AlCN using amino alcohols and BINOLs as catalysts, published in 2010-06-28, which mentions a compound: 119707-74-3, mainly applied to phosphonyl imine preparation diethylaluminum cyanide chiral catalyst Strecker cyanation; aminonitrile phosphonyl derivative stereoselective preparation deprotection diamine auxiliary recovery; amino alc binaphthol stereoselective Strecker cyanation catalyst, Synthetic Route of C20H12Br2O2.
The asym. catalytic Strecker reaction of achiral N-phosphonyl imines with Et2AlCN has been established. Both free amino alcs. and BINOLs have been proven to be effective catalysts to afford excellent enantioselectivities and yields. The N-phosphonyl group can be readily cleaved under mild conditions and enable purification of crude products by simple washing with hexane. The cleaved N,N-dialkyl diamine auxiliary can be recovered quant. via n-BuOH extraction The scope for both N-phosphonyl imines and catalysts was vastly studied for this new catalytic system.
Here is a brief introduction to this compound(119707-74-3)Synthetic Route of C20H12Br2O2, if you want to know about other compounds related to this compound(119707-74-3), you can read my other articles.
