Enantioselective total synthesis of (2R,3R,6R)-N-methyl-6-(deca-1′,3′,5′-trienyl)-3-methoxy-2-methylpiperidine, an insecticidal alkaloid
摘要:
An insecticidal piperidine alkaloid, (2R,3R,6R)-N-methyl-6-(deca-1',3',5-trienyl)-3-methoxy-2-methylpiperidine, was efficiently synthesized in a stereoselective manner starting from D-alanine. Chiral center at C-6 was controlled by hydrogenation of imine and side chain was introduced by Julia olefination. The absolute configuration of natural product was determined to be 2R, 3R, 6R.
