Reactivity of the Mitsunobu reagent toward 3-formylchromones: a strategy for the one-pot synthesis of chromeno[2,3-c]pyrazolines and chromeno[2,3-e]tetrazepines
摘要:
The zwitterionic intermediates generated from dialkyl azodicarboxylates and triphenylphosphine displayed excellent reactivity toward 3-formylchromones to afford chromeno[2,3-c]pyrazolines and chromeno[2,3-e]tetrazepines. (C) 2011 Elsevier Ltd. All rights reserved.
