Abstract

Partially saturated furo[3,4-c]thieno[2,3-d]pyrazoles (7-10) have been submitted to 1,3-dipolar cycloaddition with a variety of nitrilimines. The competitive formation of products due to the dipolar attack at different dipolarophilic sites has been observed. The experimental evidence is discussed by taking into account electronic features of the reactive species as well as their steric encumbrance.
