New routes for synthesis of branched functionalized benzenoid compounds by using tetrachlorosilaneethanol reagent
摘要:
The successive reactions of some cyclic ketones with aryl methyl ketones mediated by tetrachlorosilane-ethanol, provide an attractive and convenient route to branched functionalized benzenoid compounds. Selective unsymmetrical branched triarylbenzenes have synthesized by inducing the reaction of ketones with dypnones in quantitative yields. (C) 1997, Elsevier Science Ltd.

Abstract Lewisacid ZnCl2 promoted cyclization protocol to 4H-chromenes is accomplished, using readily available phenols and acetophenones as starting materials. Interestingly, the process is feasible under the solvent free environment. Synthesis of a variety of 4H-chromenes have been accomplished using this strategy. In addition, this concept is extended to the synthesis of ortho-benzylphenols by
