Highly diastereoselective synthesis of new chromenylaminoanthraquinones through a one-pot, three-component hetero Diels-Alder reaction

A new and efficient, diastereoselective, one-pot synthesis of chromenylaminoanthraquinones derivatives through hetero Diels-Alder reaction of 1-aminoanthraquinone and salicylaldehydes with electron-rich alkenes is reported.
