Intramolecular carbocupration reaction of unactivated alkynes bearing a stabilized nucleophile: Application to the synthesis of iridoid monoterpenes
摘要:
The copper-promoted cycloisomerization of unsaturated alkynes bearing a stabilized nucleophile is described, providing a novel synthesis of various iridoid monoterpenes. (C) 1999 Elsevier Science Ltd. All rights reserved.
