Aminoalkylated carane-type aziridines were synthesized via epoxidation of (+)-3-carene by H 2 O 2 solution (7%) in EtOAc catalyzed by α-Al 2 O 3 nanoparticles, opening of the epoxide by NaN 3 , and cyclization of the azidoalcohol by Ph 3 P followed by condensation of the resulting aziridines with formalin and secondary amines. The cytotoxicity of the aminoalkylated aziridines with heteroorganic substituents increased on going from a five-membered pyrrolidine ring substituent to a six-membered piperidine ring and decreased sharply upon replacing a piperidine by a morpholine ring or increased on going to a piperazine ring. The structures of products were established using IR and NMR spectroscopy and an X-ray crystal structure analysis. . |
