Enantioselective synthesis of (R)-(+)-β-piperonyl-γ-butyrolactone
摘要:
Lactone (R)-(+)-1, was prepared from (2S)-(-)-2-allyl-[3',4'-(methylenedioxy)phenyl]propan-1-ol(7). This intermediate was synthesized by two complementary pathways, using as the key steps the diastereoselective alkylation of esters 4 and 5, respectively.
