A series of aryl-or aralky-substituted 2-amino-3, 4-dihydroquinazolines and related compounds were synthesized. The compounds were evaluated for inhibitory activity towards collagen-and ADP-induced aggregation of rat blood platelet in vitro and ex vivo. A group of 3-benzyl-substituted derivatives had potent activity. The structure-activity relationships are discussed.

catalyzed benzylic Csp³–H bondactivation of alkylarenes and N-benzylamines under metal-free conditions was developed. This organocatalyzed oxidative transformation afforded the corresponding carbonyl derivatives in good to excellent yields. A variety of alkylarenes and N-benzylamines were tolerated under the optimized reaction conditions. The established method was further extended to the synthesis of biologically
