Meyer–Schuster rearrangement of 3°-propargyl alcohol to the corresponding α,β-unsaturatedcarbonylcompoundsunder SOCl2 catalysis has been reported. Terminal and internal propargyl alcohols efficiently participated in the reaction. Furthermore, we have demonstrated the synthetic utility of conjugated carbonylcompounds to access densely arene-substituted pyrazolines bearing quaternary centers by reacting
