A nitrogen-containing superbase such as TMG was found to be an effective catalyst for the reaction between N-diphenylphosphinoyl imines and nitroalkanes. Exploiting a protocol that avoids the use of any solvent also during workup procedure, we synthesized a series of β-nitroamines in excellent yields and high diastereomeric ratios. These results, combined with the capability of the indium in conjunction
