Py. Lin et al., NEW CANTHARIDINIMIDES FROM CANTHARIDIN AND 2-ARYLETHYLAMINES - EFFICIENT SYNTHESIS UNDER HIGH-PRESSURE, Journal of the Chinese Chemical Society, 45(2), 1998, pp. 323-326
The new cantharidinimides 3a-j were prepared, in good to excellent yie
ld, by heating the reactents 1 and 2a-j to 200 degrees C with toluene
