  ZrOCl₂ · 8H₂O: An Efficient, Ecofriendly, and Recyclable Catalyst for Ultrasound-Accelerated, One-Pot, Solvent-Free Synthesis of 8-Aryl-7,8-dihydro-[1,3]dioxolo[4,5-g]quinolin-6-(5H)-one and 4-Aryl-3,4-dihydroquinolin-2(1 H)-one Derivatives

  摘要：

  A convenient, one-pot, solvent-free reaction of amines, aromatic aldehydes, and Meldrum's acid to form 8-aryl-7,8-dihydro-[1,3]dioxolo[4,5-g]quinolin-6-(5H)-one and 4-aryl-3,4-dihydroquinolin-2-(1H)-one in the presence of 10mol% ZrOCl2.8H(2)O under ultrasonic irradiation is described. This new protocol offers several advantages including low catalyst loading, clean reaction, easy workup, use of recyclable and ecofriendly catalyst, short reaction times, good yields, and solvent-free conditions.
