Abstract An asymmetric organocatalytic arylideneacetone–olefin [4+2] cycloaddition reaction of a variety of arylideneacetones and 1,3‐indandione with different aldehydes is reported in toluene at ambient conditions to furnish the optically pure spiro compounds, which are further converted into medicinally useful spiromentins by the Suzuki reaction. This asymmetric reaction has advantageous features such as high rate and selectivity, uses easily available substrates/catalysts, has many synthetic/medicinal applications, and gives excellent yields for generating a vast library of chiral spiro compounds.
