Novel cyclization by stannyl anion generated from (trimethylsilyl)tributylstannane (Me3SiSnBu3) and fluoride ion. Application to natural product synthesis
摘要:
Stannyl anion, generated from Me3SiSnBu3 and (Et2N)3S+TMSF2- (TASF) or CsF in DMF, was quite effective for generation of an aryl or vinyl anion, which reacted with a carbonyl group intramolecularly to provide the useful cyclized product in good yield.
