The densities of pyridine, 2-picoline, 3-picoline, and 4-picoline were measured at elevated pressures (0.1 to 40) MPa at four temperatures over the range (298.15 to 328.15) K with a high-pressure apparatus. The high-pressure density data were fitted to the Tait equation and the isothermal compre...

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 Juli...

The hydrodenitrogenation (HDN) of 2-methylpyridine and its intermediate products 2-methylpiperidine, 1-aminohexane, and 2-aminohexane was studied.
