Abstract
Results Syntheses of Hydroboration Substrates. In order to test the interannular directing effects of stereochemically defined carbonyl and hydroxyl groups, a series of functionalized cyclohexylcyclohexenes (C12) and 1, 3-di-cyclohexen-1-ylcyclohexanes (c18) was required. The Clz and C18 manifolds were entered simultaneously by a onepot aldol condensation/ dehydration of cyclohexanone, according to the method of Plesek (Scheme I). 8 ...
