Diastereoselective [3 + 3] cycloaddition reaction of 2-arylideneindan-1,3-diones with β-naphthols: Efficient assemble of immunosuppressive pentacyclic chromanes
A base promoted diastereoselective formal [3 + 3] cycloaddition reaction of 2-arylideneindan-1,3-diones with β-naphthols towards the synthesis of functionalized pentacyclic indeno[1,2-b]chromen-(4bH)-ones has been developed. This methodology is appreciated in terms of diastereoselectivity and mild c...
