An efficient synthesis of pyrano [4,5-c] pyrrole derivatives through microwave—accelerated intramolecular Knoevenagal hetero Diels–Alder reaction
摘要:
Synthesis of novel pyranopyrrole derivatives has been achieved by a one-pot IMHDA reaction of N-substituted aldehydes with various diones in the presence of ethylene diaminediacetate (EDDA) in excellent yields under mild conditions. (C) 2009 Elsevier Ltd. All rights reserved.
