Abstract

An efficient acidic functionalization of mesoporous silica LUS-1 (Laval University silica) was carried out by grafting and oxidation of (3-mercaptopropyl)trimethoxysilane. The functionalized LUS-1 was characterized by different methods such as TGA, XRD, BET and SEM methods and its catalytic activity for one-pot synthesis of xanthene derivatives via the three-component condensation reaction of aromatic aldehydes and dimedone has been reported. The short reaction time, excellent yields, simple work-up procedure, and environmentally friendly conditions are particular advantages of this method. Antibacterial and antifungal activities of synthesized compounds were measured against gram-positive and gram-negative bacteria and fungus. Only compound 9-(2,4-dichlorophenyl)-3,3,6,6-tetramethyl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione (3h) showed activity against Bacillus subtilis.
