Thionation of ω-acylamino ketones with Lawesson's reagent: Convenient synthesis of 1,3-thiazoles and 4H-1,3-thiazines

The reaction of ω-acylamino ketones with Lawesson's reagent (=2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide; LR) is described. Treatment of 2-acylamino ketones 1 (n = 0) with LR gave 1,3-thiazole derivatives 3 in good yields (Scheme 1
