Efficient Addition Reaction of Bromonitromethane to Aldehydes Catalyzed by NaI: A New Route to 1-Bromo-1-nitroalkan-2-ols under Very Mild Conditions
2006
A catalytic NaI-mediated novel synthesis of 1-bromo-1-nitroalkan-2-ols was carried out by reaction of bromonitromethane with a variety of aldehydes, under very mild conditions. When the reaction was performed with chiral N,N-dibenzyl alaninal, the corresponding enantiopure (1S,2S,3S)-3-dibenzylamino-1-bromo-1-nitrobutan-2-ol was obtained with good stereoselectivity. The structure of this enantiopure bromohydrin was established by X-ray analysis.
