most efficient methods for amine synthesis. Herein we report a practical homogeneous DRA procedure utilizing iridium catalysis. Applying simple, readily available and inexpensive PPh3 and alike ligands along with iridium at a low loading, aldehydes and ketones reductively coupled with primary and secondary amines to efficiently form structurally and functionally diverse amine products, including a set
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.

to 4-amino-N-(1-phenylethyl)benzamide, 1, were prepared in a study on the relationship of structure to anticonvulsantactivity in this compound. Acylation and alkylation of the amino group of 1 resulted in almost total loss of anticonvulsantactivity. Insertion of a methylene between the 4-amino group and the aromatic ring of 1 produced a slight increase in anticonvulsant potency and a significant increase
