Efficient access to virtually enantiopure α-dialkyl-, α-acetoxy-, and α-acetamido esters
摘要:
Addition of acyclic chiral beta-enamino ester (S)-1 to alpha-methyl-, alpha-acetoxy-, and alpha-acetamido acrylates 2 gave with good yields, and with de greater than or equal to 95 % the corresponding Michael adducts (S, S)-3. (C) 1997 Published by Elsevier Science Ltd.
