A facile synthesis of β-allenyl furanimines via Pd-catalyzed cyclization of 2,3-allenamides with propargylic carbonates
摘要:
The Pd(OAc)(2)/TFP-catalyzed cyclization reaction of 2,3-allenamides in the presence of propargylic carbonates provides an efficient route to beta-allenyl furanimine derivatives. Preliminary mechanistic study showed that this reaction was probably initiated by Pd(0) species. (C) 2011 Elsevier Ltd. All rights reserved.
