No full textA novel and efficient method for
the synthesis of diversely functionalized
furans is developed via DBU-mediated tandem Michael addition/5-exo-dig-cycloisomerization of enynes and keto-methylenes.
This [3 + 2]-annulation is operationally simple under metal-free reaction
conditions with 100% atom economy and broad substrate scope
