An efficient and convenient route for the preparation of natural and unnatural histidine by asymmetric hydrogenation with rhodium-phosphine complexes is described. The reductions were performed in the presence of HBF4 to generate an essential imidazolyl cation. Stereoselective incorporation of D2 in the α,β-positions was obtained by catalytic deuteration in the presence of MeOD.
