The combination of an aldehyde, bromonitromethane, and p-methoxyaniline in the presence of tin(II) chloride and titanium tetraethoxide allows a straightforward access to β-nitroamine derivatives. The use of solid paraformaldehyde results in the amino methylation of methylnitronate. On the other hand, chiral sugar-derived aldehydes furnished the corresponding nitrosugars in high yields and stereoselectivities
