No. WO97/44319 PCT Pub. Date Nov. 27, 1997A process for preparing libraries of indole compounds by solid phase synthesis in the presence of organometallic catalysts. The resulting compounds have a very high purity degree, which allows biological testing on the crude products with a high confidence degree, without any cross contaminations.
