Dabco-Catalysed Reactions of Salicylaldehydes with Acrylate Derivatives
摘要:
Treatment of salicylaldehydes with acrylate derivatives in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) has been shown to afford both coumarin and chromene derivatives, and factors influencing the product distributions have been investigated.
