K. Yasue et al., REGIOSELECTIVE COUPLING REACTION OF ALLYLIC BARIUM REAGENTS WITH EPOXIDES, Bulletin of the Chemical Society of Japan, 70(2), 1997, pp. 493-497
The regioselective coupling reaction of epoxides with allylic barium r
eagents was achieved. All reactions resulted in high yields with remar
kable ct-selectivities. 2-Propynylbarium reagent afforded exclusively
the corresponding acetylenic alcohol.
