Calcium Hydroxide Is an Efficient Catalyst for Synthesis of Polyhydroxy Chalcones
摘要:
Calcium hydroxide was found to be an efficient catalyst for synthesis of polyhydroxy chalcones. This method has been employed to synthesize various 2,4-dihydroxychalcones having various substituents on the B ring. The merits of this method include shorter reaction time, inexpensive and easily available catalyst, high yield, and easy workup compared to other reported methods.
