Gold-catalysed intramolecular trans-allvlsilylation of alkynes forming 3-allyl-1-silaindenes

摘要

3-AUyl-1-silaindenes are synthesised from alkynes having an allylsilane moiety by a gold-catalysed intramolecular trans-allylsilylation reaction.rnEnyne cycloisomerisation reactions catalysed by electrophilic transition metal complexes have emerged as a powerful and efficient method for the construction of complex cyclic structures. Yamamoto and his co-workers reported an interesting example using an alkyne tethered to an allylsilane moiety.
