One-pot chemoselective synthesis of 2,4,6,8-tetrasubstituted quinazolines via microwave-assisted consecutive bis-SNAr/Bis-Suzuki-Miyaura cross-coupling reactions

A practical and efficient synthesis of 2,4,6,8-tetrasubstituted quinazolines through one-pot chemoselective sequential bis-SNAr/bis- Suzuki-Miyaura reactions under microwave irradiation is presented. The bis-SNAr reaction occurs selectively at the C-2 and C-4 positions of 6,8-dibromo-2,4-dichloroquinazoline and the bis-Suzuki-Miyaura cross-coupling at C-6 and C-8. This procedure affords convergent synthesis of polysubstituted quinazoline derivatives in high yields in very few steps and tolerates a wide range of boronic acids and amines.
