Alkyl Ethers

Microwave-assisted three-component reaction has been established for the synthesis of aryl alkyl ethers. The reaction was carried out under solvent free conditions in the presence of N-methylimidazole and dialkylacetylenedicarboxylate to furnish a novel approach to O-alkylation of phenol derivatives in high yield

LaCl3/ClCH2COOH was used as an efficient, and recyclable catalytic system for synthesis of 11H-benzo[a]xanthene-11-one, hexahydro-1H-xanthene- 1,8(2H)-dione and 11-aryl-10H-diindeno[1,2-b:2?,1?-e]pyran-10,12(11H)-dione derivatives via a one-pot three-component reaction of aldehydes, 2-naphthol, and cyclic 1,3-dicarbonyl compounds. The reactions proceeded rapidly at 70?C under solvent-free conditions and the desired products were obtained in good to excellent yields.

A novel synthesis of 2-phenylH-imidazio[1,2-α] pyridines is described from a one-pot, three-component reaction between pyridine, guanidine (urea or thiourea) and α-bromoketones under microwave irradiation and solvent-free conditions in excellent yields.

Cerium Iv Ammonium Nitrate

Predominant ortho-selective mononitration of low-melting and liquid phenols and hydroxycoumarins in moderate to high yields has been accomplished upon grinding with solid cerium (IV) ammonium nitrate (CAN). Microwave-assisted expeditious CAN-mediated nitration of relatively high melting phenols and hydroxycoumarins with high efficiency and selectively under solvent-free conditions has been also developed to address the problems of sluggishness and low yield for these reluctant substrates.
