The stereoselective synthesis of tetrasubstituted alkenylboronates was established via the lithiation/nucleophilic addition reaction of 1,1-orizanodiboronates to carbonyl compounds. The present approach enables the facile and practical synthesis of tetrasubstituted olefins, which are useful synthetic intermediates for further functionalizations.

bifunctional reagents that can be applied for the synthesis of simple to complex skeletons. Herein, we report a Pd-catalysed hydrogenation method for the synthesis of gem-diborylalkanes from the corresponding gem-diborylalkenes, which are themselves prepared from the corresponding aldehydes and ketones using known procedures. In addition, transformations of two representative gem-diborylalkane products
