Ultrasound promoted efficient method for the cleavage of 3-aryl-2,3-epoxyl-1-phenyl-1-propanone with indole
摘要:
An efficient synthesis of 3-aryl-3-hydroxy-2-(1H-inclol-3-yl)-1-phenyl-1-propanone via the cleavage of epoxides with indole promoted by ultrasound irradiation was carried out in good yields by using montmorillonite K10-ZnCl2 within 2-5 h at room temperature. This method provides several advantages such as operational simplicity, high yield and mild conditions. (C) 2009 Elsevier B.V. All rights reserved.
