CATIONIC CYCLIZATION OF GERANONITRILE AND RELATED COMPOUNDS VIA THEIR BROMOHYDRINS: APPLICATION TO THE SYNTHESIS OF (+/-)-SNYDEROLS

Murai, Akio,Abiko, Atsushi,Kato, Koji,Masamune, Tadashi

, p. 1125 - 1128 (2007/10/02)

Cationic cyclization of bromohydrins of geranonitrile and homogeranonitrile in the presence of boron trifluoride complexes proceeded smoothly, giving mixtures of bromo cyclic olefins in satisfactory yields.This cyclization method was applied to the synthesis of (+/-)-snyderols.
