An Efficient Route to Tetrahydroindeno[2,1-b]pyrroles via a Base-Promoted Reaction of (E)-2-Alkynylphenylchalcone with 2-Isocyanoacetate
摘要:
A base-promoted cascade reaction of (E)-2-alkynylphenylchalcone with 2-isocyanoacetate provides a novel and efficient route for the synthesis of tetrahydroindeno[2,1-b]pyrroles. The reaction proceeds smoothly in air under mild conditions with high efficiency.
