MARKOVNIKOV VINYLBORINATES FROM 9-OXA-10-BORABICYCLO[3.3.2]DECANES
摘要:
Alkylborinates 1 react with alpha-methoxyvinyllithium (LiAMV) to produce stable ''ate'' complexes, 2, which undergo BCS-induced alkyl group migration providing new air-stable vinylborinates, 3. These intermediates which are readily converted to either unsymmetrical 1,1-disubstituted alkenes (7) via the Suzuki-Miyaura coupling or, oxidatively, to methyl ketones, (8), one of which was converted to the antihistaminic drug, metron S, 10.
