Aza Hopf cyclization: synthesis and reactivity of cyclic azadieneynes
摘要:
Nine- and 10-membered azadieneynes have been synthesized for the first time via an intramolecular aza Wittig reaction. The compounds undergo Hopf cyclization under ambient conditions to the hydroxy dihydroisoquinoline derivatives. (C) 2009 Elsevier Ltd. All rights reserved.
