摘要

Recently, it has been shown that under microwave irradiation in dry media a number of alcohols and phenols could be easily O-alkylated, 12 and aromatic aldehydes could undergo condensation 13 and cyclocondensation reactions. 14 Since, more recently, Varma et al. have reported the preparation of 2-aroylbenzo[b]furans using microwave irradiation to drive the condensation of α-tosyloxyketones with salicylaldehyde derivatives on potassium fluoride doped alumina, ...
