Synthesis of homochiral 4-amino-4-carboxy-2-phosphonomethylpyrrolidines via a diastereoselective bucherer-bergs reaction of 4-oxopyrrolidine derivative: Novel conformationally restricted AP 5 analogues
摘要:
Asymmetric synthesis of 4-amino-4-carboxy-2-phosphonomethylpyrrolidines 1 and 2, which can be viewed as novel conformationally restricted analogues of 2-amino-5-phosphonopentanoic acid (AP 5) incorporated into the pyrrolidine ring, was achieved from trans-4-hydroxy-L-proline as a homochiral starting material using the diastereoselective Bucherer-Bergs reaction of(2S)-1-benzyl-2-[(diisopropylphosphonyl)methyl]-4-oxopyrrolidine 12.
