Abstract Homogeneous asymmetric hydrogenation of a wide range of methyl and tert-butyl (Z)-2-(acylamino)-3-(heteroaryl) acrylates (see 1a–f and 2a–d, f, g, resp.) catalyzed by diphosphinerhodium catalysts was studied for the synthesis of enantiomerically pure 3-furyl-, 3-thienyl-, and 3-pyrrolylalanines (see 3a–f, and 4a–d, g; Scheme 1). The precursors, the (Z)- α-amino-α, β-didehydro esters 1a–f and 2a–d, f, g were prepared in high yields using the ...
