摘要

A new C,O-cyclodialkylation of dilithiated cycli #beta#-ketoesters and #beta#-keto sulfones with 1,4-dibromo-2-butene is reported which results in regio- and diastereoselective formation of 2-vinyl-2,3,3a,4,5,6-hexahydro-2,3-benzofurans.The products could beefficiently transformed into functionalized bicycol[3.2]octan-8-ones by a palladium-catalyzed with high stereospecifity to give exclusively the endoconfigured diastereomers.The bicyclo[3.2.1]octane skeleton is present in a large number of pharmacologically important natural products.
