Iodine-catalyzed intermolecular hydroamination of vinyl arenes
摘要:
The vinyl arenes undergo smooth hydroamination with sulfonamides in the presence of 10 mol% of iodine to furnish tosyl and mesyl-protected secondary amines in excellent yields ill Short reaction times. The use of inexpensive and readily available molecular iodine makes this method quite simple, more convenient, and practical. (C) 2009 Elsevier Ltd. All rights reserved.

A series of N-benzylbenzenesulfonamides were synthesized and their biological activities were tested. Among these compounds, N-(2,3-epoxypropyl)-N-(α-methylbenzyl)benzenesulfonamide derivatives were found to be the most active against barnyardgrass and to have physiological selectivity between barnyardgrass and rice plants.
