摘要: Abstract Stereoselective synthesis of two 3-aminodeoxystatine derivatives was achieved. Chiral γ-amino-α,β-unsaturated esters containing an N -aminomethyl group undergo the stereoselective conjugate addition with internal carbamate or amide nitrogen nucleophile. The diastereoselectivity about 10:1 by 1 H NMR. Thus, were prepared from commercially available -Boc- l -leucine in nine steps overall yields 26% and 20% for benzyl acetamide derivatives, respectively.
