At the B3PW91/6-311+G(d,p)//MP2/6-311+G(d,p)level,molecular densities,detonation velocities,and detonation pressures of nitroso substituted derivatives of azetidine with their thermal stabilities were investigated to ...
Synthesis of N1-3-{(4-substitute daryl-3-chloro-2-oxo-azetidine)-iminocarbamyl}-propyl-6-nitroindazole 4a-- 4s was conducted by a conventional method. All the compounds were synthesized and characterized by IR, 1H N...
A convergent asymmetric synthesis of (2S, 3R, 4S, 12'R)-3-hydroxy-2-hydroxymethyl- 4-(12' -methyloctadecyl)-N-(p-tolylsulfonyl)-azetidine, a key precursor of penazetidine A, has been achieved by starting from divinylc...
