Abstract

Stille cross coupling protocols were utilized for the synthesis of 3-(biaryl)-8-oxabicyclo [3.2. 1] oct-2-ene-2-carboxylic acid methyl esters, which furnished products in high yields where in some cases Suzuki coupling under the conditions utilized provided complex reaction mixture. Samarium iodide reduction of the resulting coupling products produced both of the 2β-carbomethoxy-3-biaryl-8-oxabicyclo [3.2. 1] octane diastereomers and the 2α- ...
