CA 2077708
The present invention is directed to a new class of cyclic nitrones of the formula: (see formula I) in which R1 and R2 are each independently represented by a C1-3 alkyl or R1 and R2 together form a C2-7 alkyl chain, n is represented by an integer from 0 to 2, and R3 is repre- sented by a substituent selected from the group consisting of hydrogen, halogen, C1-4 alkyl, C1-4 alkoxy, -CF3, -OCF3 and -OH. These nitrones are useful as spin trapping agents.
