New Type

A new type of C2-symmetric chiral macrodiolides are readily obtained via chiral N,Nʹ-dioxide-scandium(III) complex-promoted asymmetric tandem Friedel-Crafts alkylation/intermolecular macrolactonization of ortho-quinone methides with C3-substituted indoles. This protocol provides an array...
