Synthesis of trans-dihydroindeno1,2-bfurans via nano gamma-Fe2O3 -quinuclidine-based catalyst in an aqueous medium

摘要

The synthesis of a series of 13 multifunctionalised dihydroindeno1,2-bfurans was achieved in a diastereoselective mariner in excellent yield by reacting 1,3-indanedione, an aryl glyoxal and a pyridinium ylide in the presence of a nano gamma-Fe2O3-quinuclidine-based catalyst in an aqueous medium.
