The effect of Lewis acids on the pinacol homocoupling reaction of aldehydes promoted by samarium diiodide

The effect of various Lewis acids on the samarium diiodide promoted pinacol homocoupling of aldehydes was investigated. The reaction of benzaldehyde proceeded with fair to good 1,2-anti-stereoselectivity, while in the case of other aromatic and aliphatic aldehydes syn-stereoselectivity was generally observed. Chiral α-alkylaldehydes allowed for an almost complete stereocontrol favoring syn-1,2-diols.

SYNTHESIS OF BENZOFUROBENZOFURAN AND BENZOFUROBENZOFURAN

A convenient method was developed for the synthesis of benzofurobenzofuran and benzofurobenzofuran by the structurally directed heterocyclization of hydrosalicyloin to 4b,9b-dihydrobenzofurobenzofuran or 5a,10b-dihydrobenzofurobenzofuran and their subsequent homolytic bromination and dehydrobromination in the presence of a base.The stuctures of the cyclization products are determined by the nature of the dehydrating agent.The possible mechanism of the cyclization of hydrosalicyloin in the presence of acids is disscused.
