Stereoselective Synthesis of Tetrasubstituted Alkenylboronates via 1,1-Organodiboronates
摘要:
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.
