Abstract
3-Iodopyrazolo[1,5-a]pyrimidines 3 were easily obtained by direct iodination of pyrazolo[1,5-a]pyrimidines 2 with NIS and could be transformed into a series of new substituted 3-alkenyl-pyrazolo[1,5-a]pyrimidines 5 by Heck cross-coupling.
Key Words
heterocycles - pyrazolo[1,5-a]pyrimidines - iodination - Heck reaction
