Synthesis and chemistry of new spiro-Delta(1)-pyrazoline

[摘要]：In explorations of syntheses and chemistry of spiroheterocycles, we found that the reaction of 2-diazopropane with (E)-a-arylidenepyrrolin-2-one, (E)-a-arylidene-?-butyrolactone, and (E)-arylidene-N-arylsuccinimide derivatives produced spiro-?1-pyrazolines. The photolysis of ?1-pyrazolines has led to cyclopropanes. The structures of the obtained adducts have been assigned by means of spectroscopic measurements. J. Heterocyclic Chem., (2011).
