摘要：
The reaction of beta-arylacryloyloxiranes with tosylhydrazine leads to unexpected 5-hydroxysubstituted Delta(2)-pyrazolines. A series of 3-styryl substituted pyrazoles and 5-amino-Delta(2)-pyrazolines were synthesized from the 5-hydroxy-Delta(2)-pyrazolines. The mechanism of this process has been proposed based on current and previous results.
