A convenient synthesis of 1,5-diarylpyrazoles from Baylis-Hillman adducts using HY-zeolite
摘要:
A facile and convenient protocol was developed for the synthesis of 1,5-diarylpyrazoles using Baylis-Hillman adducts in the presence of HY-zeolite as an efficient recyclable heterogeneous catalyst in reasonable reaction times (1.5-2.5 h) and high yields (78-90%).
