The recently described pressure reaction in the presence of trithylamine with subsequent thermal (200°C) cyclization provided 13N-pyridylcantharidinimides 4a-4m from aminopyridines and cantharidin in yields of 15–83%. 2-Amino-3,5-dichloropyridine failed to yield 4n.

Modification of the cantharidinimide structure led to the discovery of a novel class of antitumor compounds. These cantharidinimide derivatives containing aliphartic, aryl, and pyridyl groups showed some effect in vitro against HepG2 and HL-60 cells.
