Synthesis and biological evaluation of 3-hydroxymethyl-5-(1H-1,2,3-triazol) isoxazolidines
摘要:
A synthetic approach towards a series of 3-hydroxymethyl-5-(1H-1,2,3-triazol) isoxazolidines has been reported, according to a procedure based on the cycloaddition reaction, under microwave irradiation, of a nitrone with 1-vinyl triazoles, prepared by a click reaction of azides with alkynes. Biological tests show that the synthesized compounds are able to inhibit proliferation of follicular and anaplastic human thyroid cancer cell lines, with IC50 values ranging from 3.87 to 8.76 mu M. The obtained compounds induce caspase-3 activation and DNA fragmentation prevalently in follicular human thyroid cancer cell lines. (C) 2013 Elsevier Ltd. All rights reserved.

Nitro-substituted N-vinyl-1,2,3-triazole derivatives were synthesized by the vinyl exchange reaction. The process was promoted by the catalytic system mercury(II) acetate-trifluoroacetic acid. This system is universal, and it can be used in the synthesis of vinylazoles having two, three, and four nitrogen atoms in the ring.
