One-pot synthesis of 2H-thiopyrans from β-amino enones

A one-pot synthesis of 2 H -thiopyrans from β-amino enones has been developed. Sequential treatment of β-amino enones with the Lawesson’s reagent and electron-deficient dienophiles (maleic anhydride and maleimides) in dichloromethane gave 2 H -thiopyran derivatives in 25—62% yields.
